You have decided to buy a used car. the dealer has offered you two options: (fv of $1, pv of $1, fva of $1, and pva of $1) (use the appropriate factor(s) from the tables provided.)
a. pay $500 per month for 20 months and an additional $10,000 at the end of 20 months. the dealer is charging 24 percent per annum.
b. when you buy the car, pay cash equal to the present value of the payments in option (a).
determine how much cash the dealer would charge in option (b).

$21,635.14

Explanation:

In order to calculate present value of the annuity and future value, following formula will be used:

PV = Present Value

PMT = Annuity Payment

r = Interest Rate

FV = Future Value

n = Number of periods

Since the payment is monthly, the interest rate will also be calculated on a monthly basis:

Interest rate = 24%/12 = 2% per month

Solution:

500 (1+(1/(1+0.02)^20)/0.02 + 20000/(1+0.02)^20 = 21,635.14

Or

A finance calculator can also be used to calculate the present value

Following instructions needs to be inserted

I/Y = 2%

n = 20

PMT = 500

FV = 20,000

Press CPT then PV

answer; strategic planning;

consumer credit. an advantage is that it allows consumers to afford expensive goods and services now, increasing their standard of living. however, a disadvantage is that it creates a trap for debt, if people do not have self control, they may see themselves filing personal bankruptcy.
