loris [4]

Answer:

(A)

Step-by-step explanation:

Cost of car = $21,349

Down payment = $3000

Remaining amount left = $18,349

Monthly payments (A) = $352

n = Total periods = 5years = 5*12= 60

P(loan amount) = 18,349

r = rate of interest monthly = r/12

Using formula, A = \frac{P\frac{r}{12} }{1-(1+\frac{r}{12})^{-60} }

352 = [tex]\frac{18349\frac{r}{12} }{1-(1+\frac{r}{12})^{-60} }[/tex

    =   0.059(approx)

Annual percentage rate = 5.9%
