Step-by-step explanation:
Store A charges $20 per t-shirt. They’re having a limited “buy 2, get one free” promotion. You could buy similar t-shirts at Store B, where each shirt is $20 but you have a coupon for $5 off every shirt. Give one good reason to buy from Store A and one good reason to buy from Store B.
Answer:
It is good to buy from Store A because you can spend $40 ($20 + $20) and get one free. And it is also good to buy from Store B because you can spend $15 ($20 - $5) for each t-shirt.
A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
It is best to buy from store A since we will spend less as compared to buying from store B.
What is a unit rate?A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
Store A:
Cost of one shirt = $20
It has a limited buy two, get one free.
To get three shirts from store A, we spend $40.
Store B:
Cost of one shirt = $20
It has a coupon of $5 off for every shirt bought.
To get three shirts from store B, we spend $45
i.e $15 + $15 + $15 = 45
We see that to get the same number of the same shirt in both stores we spend $5 less in store A.
Thus, it is best to buy from store A since we will spend less as compared to buying from store B.

Answer:
Its 15
Step-by-step explanation:
You started with $300, and you spent $115 on Jake. You also set aside money to
cover the sales tax on $300. Now it's your turn to decide exactly what you will
purchase with the money you have left. You calculated the costs and best prices
for sheets, shoes, dressers, and peaches, but you didn't buy anything yet. Now
it's time to make your purchases. Make a list of the things you will buy and how
much each items cost. Explain your purchasing decisions.
Answer:
Vehicle Sales Price $30,000
Trade-In Value ($5,000)
Rebate ($1,000)
Taxable Amount $24,000
Taxable Amount * 5% $1,200
Step-by-step explanation:
The vehicle sales price is the cash price of the vehicle including any up charges that increase the vehicle price. Taxable up charges include accessories, document fees, transportation fees, anti-theft devices, and more. The sales tax rate is always the rate charged in the purchaser's county of residence, as indicated by the address on the title.
If the purchase was made out of state, the tax rate will be determined by the purchaser's county residence. Click for more info on out of state purchases.
For example, if someone from Converse County; 5% (6% from April 1, 2013 through November 30, 2015); purchases a vehicle in Denver (7%), the purchaser would pay 5% (6% April 1, 2013 to November 30, 2015).
Important: Wyoming law requires that a bill of sale must be presented to pay sales tax when a vehicle is purchased from a dealer. When a vehicle is purchased from an individual, no bill of sale is required.
The amount of sales tax due depends on:
- Sales price of the vehicle, and
- The applicable sales tax rate
First, see how much money you can actually spend
300-115-21=164
ok so u have $164
ok now just choose stuff you wanna buy, I will just buy the list of things in the question (sheets, shoes, dressers, and peaches) because I already know the price of them
so the sheet is $18 and buy 1 get 1 50% off, u need 3, so 18x2+9=$45
shoes are 3 for the price of 2 and each pair is 10 bucks, so 3 will be the price of 2 shoes which is 10x2=$20
For dressers, only 2 people want their own so we only need 2, dressers are 12% off $32 which is $28.16 each so 2 of them is 28.16x2=$56.32
In step 3 part b it says how much a dozen costs so im going to assume the family wants a dozen
since 3 is $2 a dozen will be $8 so $8 dollars for peaches
Now add the prices up to find the total money we spent on other things other than on Jake or tax. so 45+20+56.32+8=129.32
since we started with 164 we have enough money for these items, the rest of the money just goes to the family for them to spend i guess, so 164-129.32=$34.68 are given to the family for them to spend.

If a+b>a−b, which of the following must be true?
(A) a>b (B) a=b (C) a> 0 (E) b > 0
Answer:
(E) b > 0
Step-by-step explanation:
a+b > a-b
Subtracting a on both sides,
a+b-a > a-b-a
b > -b
Adding b on both sides,
b+b > b-b
2b > 0
b > 0

The average cost of a bag of popcorn at the movie theater was $3.50 in 1995 and $4.75 in 2015. Find the percent of change in the price of a bag of popcorn from 1995 to 2015 and classify as a percent increase or percent decrease.

D. 35.7% increase
The large bag of popcorn cost $8.50 while the small bag of popcorn cost $5
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.
Here, we have,
Variables are letters use to represent number in an equation.
Therefore,
Let
x = cost of small bag of popcorn
y = cost of large bag of popcorn
A large bag of popcorn cost $3.50 more than a small bag of popcorn. Therefore,
y = 3.50 + x
A movie theatre sells 12 large bags of popcorn and 25 small bags of popcorn for $227. Therefore,
12y + 25x = 227
Let's combine the equation
y - x = 3.50
12y + 25x = 227
12y - 12x = 42
37x = 185
x = 185 / 37
x = 5
Therefore,
y = 3.50 + 5
y = 8.50

The ratio of 7:8:9=__:12:__
What do the blank spaces represent?
Answer:
10.5; 13.5
Step-by-step explanation:
7:8:9=_:12:_
8 is corresponding to 12
12/8=1.5
8*1.5=12
So, multiply 7 & 9 by the same value (1.5) to get the answer.
7*1.5=10.5 or 10 1/2
9*1.5=13.5 or 13 1/2
The ratios are:
7:8:9=10.5:12:13.5
The blank spaces are 10.5 and 13.5 respectively.

a country will produce 3000 missels this year. each of the short range missles costs $200,000 to produce. Each of the medium range missles cost $300,000 to produce. the ratio of the number of short range to medium range missles to long range missles the country plans to produce this year is 3:3:4. the country plans to use $870,000,000 to produce these missles. how much does it cost to produce longe range missles?
Answer:
Step-by-step explanation:
3000/10=300 300=10% of total missiles
300*3=900(30%) That country (assuming it is Iran) would produce 900 short missiles and 900 medium missiles. 3000-900(2)=3000-1800=1200.
Iran will produce 1200 long range missiles.
For the cost of the missiles,
200,000*900=180,000,000. 300,000*900=270,000,000.
870M-(180M+270M)=870M-450M=420M
420,000,000/1200=350,000.
Long Range Missiles are $350,000 each... got me thinkin bout buying some...
