you are a freelancer and were offered two gigs. one will pay you $25,000today and the other will pay you $5,000 per year over the next six years. assuming your required return is 8%, which gig should you accept, assuming you are in it just for the money?
The preferred gig is the first one since its today's worth is greater than the today's value of the second gig
What is the today's worth of $5000 each year?
The worth of the second gig, which pays $5000 every year for the next 6 years in today's dollar is the present value of all the six annual cash flows discounted using the present value formula of an ordinary annuity as shown below:
PV=PMT*(1-(1+r)^-N/r
PV=present value of annual payments for 6 years=unknown
PMT=annual payment=$5000
r=required return=discount rate=8%
N=number of annual cash flows=6
PV=$5000*(1-(1+8%)^-6/8%
PV=$5000*(1-(1.08)^-6/0.08
PV=$5000*(1-0.630169626883105)/0.08
PV=$5000*0.369830373116895
/0.08
PV=$23,114.40
The fact that the present value of the second option which pays $5000 annually is lesser than the amount receivable immediately, which is $25,000, hence, the first gig is preferred

Consider the following advertisement.Which of the following calculations represents the cost of 2 dozen iris bulbs?
Answer:
C: (6 x $5)+(6 x $4)+(12 x $3)
Explanation:
The total number of bulbs bought = 2 dozens = 2 x 12 = 24
• The cost per bulb for the first half-dozen = $5
[tex]\text{Cost for the first half-dozen=6 x \$5}[/tex]• The cost per bulb for the next half-dozen = $4
[tex]\text{Cost for the next half-dozen=6 x \$}4[/tex]Out of 24 bulbs, we have calculated the cost for 12.
• The number of bulbs left = 24 - 12 = 12.
,• Each additional bulb is $3 per bulb.
The cost for the last 12 will be:
[tex]12\times\$3[/tex]Therefore, the cost for the 2 dozen iris bulbs will be:
[tex](6\times\$5)+(6\times\$4)+(12\times\$3)[/tex]The correct choice is C.

The correct interpretation of the 95% confidence interval is that:
We are 95% sure that the true population mean widget width is between 11.5 and 27.3 units.
What is the interpretation of a x% confidence interval?The x% confidence interval means that it is x% likely that the population parameter(mean/proportion/standard deviation) is between the bounds of the confidence interval, given by a and b.
The bounds of the confidence interval are given by the estimate of the population parameter plus/minus the margin of error found from the sample size/standard deviation.
In the context of this problem, the bounds of the interval are already given as follows:

Admission to a baseball game is $4.00 for general admission and $5.50 for reserved seats. The receipts were $5196.50 for 1181 paid admissions. How many of eachticket were sold?
Given:
Admission to a baseball game is $4.00 for general admission and $5.50 for reserved seats.
Let the number of tickets of general admission = x
Let the number of tickets of reserved seats = y
The receipts were $5196.50 ⇒ 4x + 5.5y = 5196.50
The paid admissions 1181 ⇒ x + y = 1181
So, we have the following system of equations:
[tex]\begin{gathered} 4x+5.5y=5196.50\rightarrow(1) \\ x+y=1181\rightarrow(2) \\ \text{from}(2)\colon x=1181-y\rightarrow(3) \end{gathered}[/tex]Substitute with x from (3) into (1) then solve to find y
[tex]\begin{gathered} 4(1181-y)+5.5y=5196.50 \\ 4\cdot1181-4y+5.5y=5196.5 \\ 4724+1.5y=5196.50 \\ 1.5y=5196.50-4724 \\ 1.5y=472.5 \\ y=\frac{472.5}{1.5}=315 \end{gathered}[/tex]Substitute with y into equation 3 to find x:
[tex]x=1181-315=866[/tex]So, the answer will be:
The number of tickets of general admission = 866
The number of tickets of reserved seats = 315

This figure indicates that Juanita will run out of ribbon after tying 32 gift bags.
Explain about the zero of a function?A real number that fulfils the equation f(x) = 0 is a real zero of a function f(x). In other words, if f(r) = 0, we can claim that a real number 'r' is a function f(x) zero.Any substitution for the variable in a function that results in a zero answer is known as the zero. The x-intercept(s) of the function's graph, or the actual zero of a function, is the location on a graph where the function's graph crosses the x-axis.The function's zero is 32 gift bags. This indicates that Juanita will run out of ribbon after tying bows on 32 gift bags.Considering the query;
The quantity of ribbon Juanita has left after tying ribbon on gift bags is represented by the function r = 24 -0.75g.
At r = 0, the function's zero is located.
Therefore;
