Andrea is buying a car for $21,450. she will finance $16,450 of it with a 5-year loan at 2.9% apr. what will her monthly auto payment be?

To solve the problem, use the formula:
A = P (i ( 1 + i)^n) / ((1 + i)^n  - 1)
where A is the yearly payment
P is the principal amount of money
i is the annual percent rate or APR
n is the number of year

A = ( 16,450) ( 0.029( 1 + 0.029)^5)) / ( 1 + 0.029)^5  - 1)
A = 3581.68
and her payment per month is
m = 3581.68 / 12
m = $ 298.47 per month
