The bookstore at Tech purchases jackets emblazoned with the school name and logo from a vendor. The vendor sells the jackets to the store for $38 apiece. The cost to the bookstore for placing an order is S120, and the annual holding cost is 25% of the cost of a jacket. The bookstore manager estimates that 1700 jackets will be sold during the year. The Vender has offererd bookstore the following volume discount schedule. 1. Order Size Discount 1-299 300-499 500-799 800+ 0% 2% 4% 5% Determine the bookstore's optimal order quantity and the total amount annual inventory cost
By analyzing the volume discount schedule and considering the inventory costs, the optimal order quantity and the total annual inventory cost can be determined.
To find the optimal order quantity, we need to consider the volume discount schedule provided by the vendor and calculate the inventory costs for different order sizes.
The volume discount schedule offers discounts based on the order size. For orders ranging from 1 to 299 jackets, there is no discount. For orders between 300 and 499 jackets, a 2% discount is applied. For orders between 500 and 799 jackets, a 4% discount is given. And for orders of 800 jackets or more, a 5% discount is provided.
To minimize annual inventory costs, we need to find the order quantity that results in the lowest total cost, considering both the ordering cost and the holding cost. The total cost can be calculated as the sum of the ordering cost and the holding cost.
Let's analyze the options and calculate the total cost for each order quantity:
- For orders between 1 and 299 jackets, there is no discount. The total cost can be calculated as follows:
Total cost = Ordering cost + Holding cost
= $120 + (0.25 * $38 * 1700)
- For orders between 300 and 499 jackets, a 2% discount is applied. The total cost can be calculated as:
Total cost = Ordering cost - Discount + Holding cost
= $120 * 0.98 + (0.25 * $38 * 1700)
- For orders between 500 and 799 jackets, a 4% discount is given. The total cost can be calculated as:
Total cost = Ordering cost - Discount + Holding cost
= $120 * 0.96 + (0.25 * $38 * 1700)
- For orders of 800 jackets or more, a 5% discount is provided. The total cost can be calculated as:
Total cost = Ordering cost - Discount + Holding cost
= $120 * 0.95 + (0.25 * $38 * 1700)
By comparing the total costs for different order quantities, we can determine the optimal order quantity that minimizes the total annual inventory cost.
In this case, the optimal order quantity is the one that yields the lowest total cost. By comparing the total costs for different order quantities, we can determine the optimal order quantity that minimizes the total annual inventory cost.

In the last decade, there has been an increasing amount of discussion regarding whether or not
China will "catch up" with the United States in terms of output and GDP. Knowing what you do
about economic growth, what do you think? Will China eventually catch up with us? Why or
why not?
In the last decade, China's economy has grown dramatically, propelling it to the world's second-largest economy after the United States. In terms of GDP, China's economy was worth 14.3 trillion USD in 2019, accounting for roughly 16% of global GDP.
To determine whether or not China will eventually catch up with the United States, it is necessary to consider several factors that influence economic growth, such as demographics, productivity, innovation, infrastructure, and policies. While China has made significant progress in these areas, it still lags behind the United States in some crucial aspects.
Firstly, demographics are a significant factor in economic growth. China's population is aging, and its birth rate is decreasing. This could limit its labor force and productivity growth in the future. Additionally, China's population is heavily concentrated in the east, which may lead to the country's underdeveloped regions being left behind.
Secondly, innovation and productivity are essential drivers of economic growth. While China has made significant investments in these areas, it still lags behind the United States in terms of research and development spending, as well as intellectual property protections. Additionally, China's state-owned enterprises, which account for a significant portion of its economy, may not be as efficient as their private counterparts in the United States.
Thirdly, infrastructure is essential for economic growth. While China has invested heavily in infrastructure in recent years, the quality of its infrastructure remains a concern. China's infrastructure is often criticized for being expensive, low quality, and prone to corruption.
Fourthly, policies are crucial to economic growth. China's government has implemented several policies to promote economic growth, such as tax breaks and subsidies for certain industries. However, China's policies also have several drawbacks, such as state intervention, lack of transparency, and corruption.
In conclusion, it is difficult to predict whether or not China will eventually catch up with the United States in terms of output and GDP. While China has made significant progress in several areas, it still faces several challenges, such as demographics, productivity, innovation, infrastructure, and policies. Moreover, the COVID-19 pandemic has significantly impacted the global economy, including China's, making any prediction difficult to make.

A proposal has been made for improving the downtown area of a small town. The plan calls for banning vehicular traffic on the main street and turning this street into a pedestrian mall with tree plantings and other beautification features. This plan will involve actual costs of $7,500,000 and, according to its proponents, the plan will produce benefits and disbenefits to the town as follows: Benefits: Increased sales tax revenue $475,000 per year Increased real estate property taxes $300,000 per year Benefits due to decreased air pollution $80,000 per year Quality of life improvements to users $75,000 per year Disbenefits: Increased maintenance $225,000 per year b. How does the B-C ratio change for a 20-year project life? (10.7)
The B-C ratio can be used to assess the economic viability and desirability of the project. If the B-C ratio is greater than 1, it indicates that the benefits outweigh the costs, making the project economically beneficial.
To determine how the Benefit-Cost (B-C) ratio changes for a 20-year project life, we need to calculate the present value of both the benefits and disbenefits over the project's duration.
First, let's calculate the net benefits for each year by subtracting the disbenefits from the benefits:
Net benefits = Benefits - Disbenefits
Year 1: $475,000 + $300,000 + $80,000 + $75,000 - $225,000 = $705,000
Year 2: $475,000 + $300,000 + $80,000 + $75,000 - $225,000 = $705,000...
Year 20: $475,000 + $300,000 + $80,000 + $75,000 - $225,000 = $705,000
Next, we calculate the present value of each year's net benefits using an appropriate discount rate. Let's assume a discount rate of 5% for this calculation.
Present value factor for Year 1: 1 / (1 + 0.05)^1 = 0.9524
Present value factor for Year 2: 1 / (1 + 0.05)^2 = 0.9070...
Present value factor for Year 20: 1 / (1 + 0.05)^20 = 0.3769
Present value of net benefits = Net benefits * Present value factor
Present value of Year 1 net benefits: $705,000 * 0.9524 = $670,476
Present value of Year 2 net benefits: $705,000 * 0.9070 = $639,135 ...
Present value of Year 20 net benefits: $705,000 * 0.3769 = $265,797
To calculate the B-C ratio, we sum up the present value of net benefits:
Total present value of net benefits = Present value of Year 1 net benefits + Present value of Year 2 net benefits + ... + Present value of Year 20 net benefits
Total present value of net benefits = $670,476 + $639,135 + ... + $265,797
Finally, we divide the total present value of net benefits by the actual costs of the project to obtain the B-C ratio:
B-C ratio = Total present value of net benefits / Actual costs of the project ($7,500,000)

It fills standard bottles of 750 ml, and these are passed to a packing area which can form up to 20,000 cases a day with 12 bottles each. The packing area works a five-day week. The cases are taken to warehouses by a transport company whose 8 lorries can each carry 300 cases, and make up to 4 trips a day for 7 days a week. There are two main warehouses, each of which can handle up to 30,000 cases a week. Local deliveries are made from the warehouses by a fleet of small vans that can handle everything passed to them by the warehouse. What is the capacity of this distribution system in bottles/week?
The capacity of this distribution system in bottles/week is 720,000 bottles/week
The capacity of the distribution system in bottles/week can be calculated by the following steps:
Step 1: Find the daily capacity of the bottling plant Daily capacity of bottling plant = 80,000 liters/day Convert liters to ml by multiplying by 100080,000 × 1000 = 80,000,000 ml/day Number of bottles that can be filled in a day = Daily capacity/volume of one bottle= 80,000,000/750= 106,667 bottles/day
Step 2: Find the daily capacity of the packing area: Number of cases that can be formed in a day = Number of bottles/Number of bottles per case= (\frac{106,667}{12}) × 20,000= 1,777,780 cases/day
Step 3: Find the daily capacity of the transport company: Number of cases that can be transported in a day = Number of trips × Number of lorries × Number of cases per lorry= 7 × 8 × 300= 16,800 cases/day
Step 4: Find the weekly capacity of the warehouses: Weekly capacity of one warehouse = 30,000 cases/week
Total weekly capacity of the two warehouses = 2 × 30,000= 60,000 cases/week
Step 5: Find the weekly capacity of the local delivery fleet .The local delivery fleet handles everything passed to them by the warehouses.
Therefore, their weekly capacity is equal to the weekly capacity of the two warehouses. Weekly capacity of the local delivery fleet = 60,000 cases/week
Step 6: Find the weekly capacity of the distribution system Weekly capacity of distribution system = (Number of bottles per case) × (Weekly capacity of local delivery fleet)
= 12 × 60,000= 720,000 bottles/week
Therefore, the capacity of this distribution system in bottles/week is 720,000 bottles/week.

2 Question 1(Multiple Choice ) (04.06 MC) Which of the following best explains why a monetary policy cannot help a country remove the inflationary gap in the economy? O A crowding out effect reduces private investment. O An increase in taxes discourages investment in the economy. O An increase in the reserve ratio does not translate to changes in the interest rate quickly. O Buying of securities leads to a decrease in the amount of credit in the economy. O Government spends too much on the unnecessary areas.
The monetary policy cannot help a country remove the inflationary gap in the economy due to the reason that an increase in the reserve ratio does not translate to changes in the interest rate quickly.
Monetary policy is a central bank's strategic tool to control money supply, which impacts inflation, interest rates, and the overall economy. Monetary policy is divided into two categories: expansionary and contractionary.An inflationary gap is a macroeconomic condition in which the difference between the current level of real GDP and its estimated potential GDP is positive. In this state, total spending is higher than the economy's production capability. As a result, aggregate demand exceeds aggregate supply, and the price level rises.What is an increase in the reserve ratio?The reserve ratio is the fraction of deposits that banks must maintain as reserves with the central bank. A bank's excess reserves can be lent out, generating more money and contributing to economic growth. An increase in the reserve ratio decreases the amount of excess reserves available to the bank to lend.What is buying of securities?Buying of securities refers to the act of purchasing financial instruments such as stocks, bonds, or other securities. It is an investment strategy employed by investors to profit from the market's fluctuations.Buying of securities leads to a decrease in the amount of credit in the economy since investors pay cash for these securities. This diminishes the banks' reserves, and the money supply decreases as a result. Therefore, buying of securities leads to a decrease in the amount of credit in the economy.

4. Assume that an economy is initially at the long-run equilibrium, and the
short-run aggregate supply curve is derived from the sticky-price model.
a. Use the AD-AS and Phillips curve diagram to illustrate graphically how the inflation rate

b. Use the AD-AS and Phillips curve diagram to illustrate graphically how the inflation rate

AD-AS model to graphically illustrate the difference between demand-pull and cost-push inflation Demand-pull inflation and cost-push inflation are the two types of inflation. The difference between demand-pull and cost-push inflation can be graphically illustrated by the AD-AS model. A supply shock or an increase in the cost of production is the main cause of cost-push inflation. Cost-push inflation is represented by a leftward shift in the aggregate supply (AS) curve. As a result, the new equilibrium point is located at a higher price level and a lower real GDP. The increase in prices results in lower purchasing power and a decrease in demand, which is represented by a leftward shift in the aggregate demand (AD) curve. Demand-pull inflation is caused by excessive aggregate demand or a rightward shift in the AD curve. As a result, the new equilibrium point is located at a higher price level and a higher real GDP. The increase in prices results in lower purchasing power and a decrease in demand, which is represented by a leftward shift in the AD curve. When an economy is initially at the long-run equilibrium, the short-run aggregate supply curve is derived from the sticky-price model
.a) An unexpected expansionary monetary policy affects both the inflation rate and the unemployment rate in the short run and the long run. In the short run, an unexpected expansionary monetary policy leads to an increase in aggregate demand, as seen by a rightward shift of the AD curve. The increase in aggregate demand leads to an increase in the price level and real GDP. This results in a lower unemployment rate and a higher inflation rate. In the long run, nominal wages and prices increase in response to the increase in inflation, resulting in a leftward shift of the short-run aggregate supply curve. This leads to a higher price level but the same level of real GDP as before the policy change. Therefore, in the long run, the inflation rate is higher, but the unemployment rate returns to the natural rate.
b) The announcement of a credible plan of expansionary monetary policy when people have rational expectations also affects the inflation rate and the unemployment rate in the short run and the long run. In the short run, a credible plan of expansionary monetary policy leads to an increase in expected inflation, as seen by a rightward shift of the short-run Phillips curve. The increase in expected inflation leads to an increase in the actual inflation rate, as seen by a rightward shift of the AD curve. This results in a lower unemployment rate and a higher inflation rate. In the long run, nominal wages and prices increase in response to the increase in inflation, resulting in a leftward shift of the short-run aggregate supply curve. This leads to a higher price level but the same level of real GDP as before the policy change.
Therefore, in the long run, the inflation rate is higher, but the unemployment rate returns to the natural rate.

A beta of 1 indicates that the stock tends to move in line with the market, while a beta greater than 1 suggests that the stock is more volatile than the market, and a beta less than 1 indicates that the stock is less volatile than the market.
Therefore, the systematic risk associated with an individual stock is most closely identified with Beta. It provides investors with an understanding of how the stock's returns are likely to be influenced by market movements, helping them assess the level of risk associated with the stock and make informed investment decisions.

(b) Are her preferences strictly convex? If you answer yes, explain briefly (no need for a formal proof). If you answer no, provide a counterexample. (c) At Lucie's local supermarket, each candy is wrapped in 2 pieces of plastic pack- aging, and so is each piece of fruit. Her income is $60 and each (wrapped) piece of fruit and (wrapped) candy costs $4. When she chooses optimally, Lucie con- pieces of fruit, and pieces of plastic packaging. Show working/explanation for your answer. sumes pieces of candy, (d) Lucie finds a small organic market that sells 4 candies in 1 piece of plastic packag- ing, and sells fruit with no plastic packaging. Each wrapped container of 4 candies costs $20 at this market, and each unwrapped piece of fruit costs $6. When she chooses optimally, Lucie consumes pieces of candy, pieces of fruit, and pieces of plastic packaging. Show working/explanation for your answer.
Lucie's preferences are strictly monotone but not strictly convex. She optimally consumes 10 pieces of candy, 20 pieces of fruit, and 40 pieces of plastic packaging at the local supermarket, and 10 pieces of candy, 40 pieces of fruit, and 10 pieces of plastic packaging at the organic market.
Lucie's preferences are strictly monotone because she is always willing to trade one piece of fruit for one piece of candy and requires compensation of an additional piece of fruit for each piece of plastic packaging. This means that if she receives more candy or less plastic packaging, she will strictly prefer the new bundle.
However, her preferences are not strictly convex. Strict convexity implies that Lucie would always prefer a convex combination of two bundles over the bundles themselves. In this case, it is possible to construct a counterexample where a convex combination of two bundles does not yield a preferred outcome for Lucie.
In the optimal consumption at the local supermarket, each piece of candy costs $4, and each piece of fruit and plastic packaging also cost $4 due to the packaging. With an income of $60, Lucie can afford 15 candies and 15 wrapped fruits. As she values fruit more than candy, she consumes 10 pieces of candy and 20 pieces of fruit, leaving her with 20 pieces of plastic packaging to maintain the exchange rate.
At the organic market, the bundled candies come with only 1 piece of plastic packaging. With an income of $60, Lucie can afford 3 bundled candies and 10 unwrapped fruits. Since she values fruit more than candy, she consumes 10 pieces of candy and 40 pieces of fruit, which eliminates the need for plastic packaging altogether.

Q6: Based on your answers to questions 4 and 5, assuming an expected return of the market of 10.0%, should you invest in this portfolio from a risk/reward perspective?
Portfolio returns are the results obtained from a set of investments' performances. When evaluating an investment portfolio, various metrics, including the expected returns, risks, and betas of the constituent securities, are crucial. When making an investment decision, the risk-reward tradeoff is an essential consideration.
Investors must assess whether the returns obtained from an investment are sufficient relative to the risk incurred.A portfolio is equally invested in Stock A, Stock B, Stock C, and Treasury Bills (25% each). The expected returns of each of these holdings are 5%, 12%, 22%, and 1%, respectively.
The Betas for each of the stocks is as follows:
A 0.6, B 1.1, and C 2.5.The portfolio's expected returns can be calculated as follows:Portfolio's expected return = (Stock A weight × expected return of Stock A) + (Stock B weight × expected return of Stock B) + (Stock C weight × expected return of Stock C) + (Treasury Bills weight × expected return of Treasury Bills)= (0.25 × 5%) + (0.25 × 12%) + (0.25 × 22%) + (0.25 × 1%)= 10%The portfolio's expected return is 10%.
Based on the information given, the portfolio's beta can be computed as follows:Portfolio beta = (Stock A weight × beta of Stock A) + (Stock B weight × beta of Stock B) + (Stock C weight × beta of Stock C)= (0.25 × 0.6) + (0.25 × 1.1) + (0.25 × 2.5)= 1.3The portfolio's beta is 1.3.
Assuming an expected return of the market of 10.0%, an investment in this portfolio from a risk/reward perspective would be reasonable because its expected return is the same as the expected return of the market. Furthermore, given that the portfolio's beta of 1.3 is greater than the market's beta of 1.0, the portfolio will provide a better return if the market rises but will lose more if the market declines.
Thus, from a risk/reward perspective, an investment in this portfolio is reasonable when considering the market's expected return. Therefore, it can be concluded that from a risk/reward perspective, investing in this portfolio is a viable decision.

Lump Sum
Cost Plus
Unit Prices
Cost Plus contract is appropriate when the project’s actual costs and scope of work are difficult to estimate with accuracy.
The term Cost Plus Contract refers to an arrangement between a vendor and a customer in which the seller is paid for all costs incurred in completing the job in addition to a fixed profit margin. Cost Plus contracts are agreements in which the contractor is reimbursed for all of the costs incurred during the project, as well as a set fee or percentage of the total project cost. Cost-plus contracts, in general, are most commonly used when the scope of work is uncertain or when it is difficult to estimate the cost of the work to be performed because there are no baseline costs to serve as a guide. The buyer is aware of the contractor's expenses and profit margin, as well as a mutually agreed-upon fee.
In a cost-plus contract, a contractor is typically paid based on a percentage of the total project cost. A contractor's profit in a cost-plus contract is based on the total costs of the project and a percentage markup known as a fee. The fee is typically a percentage of the total costs of the project, which can range from 5 to 10%. In a cost-plus contract, a contractor must keep thorough records and provide invoices and other documentation to support the costs. This can aid in the prevention of overbilling, as the customer will be able to see all of the costs incurred in the project.

how to answer question 3 using differential analysis
(a) Saratech Company is a manufacturing company that mainly produces semiconductor products. TABLE 2 is the detail of the number of output and costs of production for the second half of 2021. The curr
market condition for the semiconductor industry is very unpredictable and the company is facing a lot of uncertainty in terms of demand and prices for their products. In order to make informed decisions, the company has decided to conduct a differential analysis of their cost structure.
Differential analysis is a tool used to identify the key drivers of cost and to determine the relative impact of each factor on the overall cost structure. In this case, the analysis will focus on the following variables:
Direct materials cost
Direct labor cost
Overhead costs
Sales volume
Product mix
The goal of the analysis is to determine which factors have the greatest impact on the company's cost structure and to identify opportunities for cost reduction.
To start the analysis, the company will first gather data on the costs of production for each of the variables listed above. This data will be used to create a cost-volume profit (CVP) chart, which is a graph that shows the relationship between the cost of production and the volume of output.
Next, the company will use the CVP chart to calculate the break-even point (BEP), which is the volume of output at which the total cost of production equals the total revenue generated by the output. The BEP will be used as a benchmark to compare the cost structure of different production scenarios.
The company will then use the differential analysis tool to identify the key drivers of cost. This will involve comparing the costs of different production scenarios and identifying the variables that have the greatest impact on the cost structure.
For example, the analysis may show that the cost of direct materials is the largest driver of cost, while the sales volume has a minimal impact on cost. In this case, the company may focus on reducing the cost of direct materials as a way to reduce overall cost.
Overall, the differential analysis will provide the company with a clear understanding of their cost structure and will enable them to make informed decisions about how to optimize their production process. This will help the company to remain competitive in the fast-changing semiconductor industry and to increase their profitability.

[Use partial derivatives, increment formula (differential), and tools of comparative statics] A consumer's utility function is given by U=x² + y2 where x and y denote the number of items of two goods Gl an G2 that are bought. P, and P, are the prices of good x and y, respectively. M is consumer income. U denotes utility. [Solve this question using Lagrange multiplier and Lagrangian function] a) Write down budget constraint and Lagrangian function. b) Solve for optimum level of x and y. They are also called demand functions of good x and y, respectively. c) Find the maximum value of U if budget constraint is 5x+5y=200.
a) The budget constraint is given by P₁x + P₂y = M, and the Lagrangian function is L(x, y, λ) = U(x, y) + λ(M - P₁x - P₂y).
b) The demand functions for good x and y are x = M / (P₁ + P₂) and y = M / (P₁ + P₂).
c) The optimum levels of x and y are x = 20 and y = 20, and the maximum value of U is 800 when the budget constraint is 5x + 5y = 200.
a) Budget constraint: The budget constraint represents the consumer's affordability based on their income and the prices of the goods. In this case, the budget constraint is given as:
P₁x + P₂y = M
Where:
P₁ = Price of good x
P₂ = Price of good y
x = Quantity of good x
y = Quantity of good y
M = Consumer income
Lagrangian function: The Lagrangian function is used to solve constrained optimization problems. In this case, the Lagrangian function is defined as:
L(x, y, λ) = U(x, y) + λ(M - P₁x - P₂y)
Where:
U(x, y) = Utility function
λ = Lagrange multiplier
b) To find the optimum levels of x and y, we need to maximize the Lagrangian function with respect to x, y, and λ while satisfying the budget constraint.
Taking partial derivatives of the Lagrangian function with respect to x, y, and λ, we have:
∂L/∂x = 2x - λP₁ = 0 (Equation 1)
∂L/∂y = 2y - λP₂ = 0 (Equation 2)
∂L/∂λ = M - P₁x - P₂y = 0 (Equation 3)
From Equation 1, we have:
2x = λP₁ (Equation 4)
From Equation 2, we have:
2y = λP₂ (Equation 5)
Solving Equations 4 and 5 simultaneously, we get:
x/y = P₁/P₂
Substituting the above ratio into Equation 3, we have:
M = P₁x + P₂y
M = P₁(x/y)y + P₂y
M = (P₁/P₂)P₂y + P₂y
M = (P₁ + P₂)y
Therefore, y = M / (P₁ + P₂)
Similarly, substituting the ratio x/y into Equation 3, we have:
x = M / (P₁ + P₂)
Hence, the demand functions for good x and y are:
x = M / (P₁ + P₂)
y = M / (P₁ + P₂)
c) To find the maximum value of U, we need to substitute the budget constraint into the utility function.
Given the budget constraint: 5x + 5y = 200, we can rewrite it as:
x + y = 40
Now, substituting x = 40 - y into the utility function U(x, y), we have:
U = (40 - y)² + y²
U = 1600 - 80y + 2y²
To find the maximum value of U, we can take the derivative of U with respect to y and set it equal to zero:
dU/dy = -80 + 4y = 0
4y = 80
y = 20
Substituting the value of y back into the budget constraint, we can find the corresponding value of x:
x + 20 = 40
x = 20
Therefore, the optimum levels of x and y are x = 20 and y = 20.
The maximum value of U is obtained by substituting these values into the utility function:
U = (20)² + (20)²
U = 400 + 400
U = 800
a) The budget constraint is given by P₁x + P₂y = M, and the Lagrangian function is L(x, y, λ) = U(x, y) + λ(M - P₁x - P₂y).
b) The demand functions for good x and y are x = M / (P₁ + P₂) and y = M / (P₁ + P₂).
c) The optimum levels of x and y are x = 20 and y = 20, and the maximum value of U is 800 when the budget constraint is 5x + 5y = 200.
