Answer:

Option B is correct

PV of annuity = $6,682.99

Explanation:

An annuity: A series of equal amount receivable or payable in the future for certain number of years is called an annuity. If the cash flows occurs at the end of the year , it is known as an ordinary annuity

The present value of an ordinary annuity is the amount that needs to be invested today to generate a series of equal annual cash flows in the future.

PV of ordinarily annuity= A × (1- (1+r)^(-n)/r

r= 3.7%/12= 0.308% . Monthly interest rate is annual rate divided by 12

n= 12× 4 = 48 (Note there are 12 months in a year)

A- 150

PV of annuity = 150× (1- 1.00308^(-48))/0.00308= 6,683.52

PV of annuity = $6,682.99

Answer:

Option B. $6,683

Explanation:

We can calculate the  payments worth to you when you enter college by multiplying the annual amount by an annuity factor

Annuity factor can be calculated for four  years as follows

DATA

Discount rate = r = 3.7%/12 = 0.00308

No. of months = 12 x 4 = 48 months

Monthly payment = $150

Future value =?

Future value = Annual payments x annuity factor

Future value = $150 x 44.5567795037(w)

Future value = $6,683

Workings

Annuity factor = [tex]\frac{1-(1+r)^-n}{r}[/tex]

Annuity factor = [tex]\frac{1-(1+0.00308)^-48}{0.00308}[/tex]

Annuity factor =44.5567795037
