Answer:
APR has he paid 5.9%
option B is correct
Explanation:
given data
Cost of car = $21,349
down payment = $3000
Monthly payments (A) = $352
time period t = 5 year = 5 × 12 = 60 months
to find out
what APR has he paid
solution
we know that we have remaining balance amount = 21349 - 3000
= $18,349
so we say that loan amount L = $18,349
here rate r = rate of interest = r/12 monthly
so we use formula amount
payment (A) = [tex]\frac{L\frac{r}{12} }{1-(1+\frac{r}{12})^{-t} }[/tex]
put all thes evalue we get
352 = [tex]\frac{18349\frac{r}{12} }{1-(1+\frac{r}{12})^{-60} }[/tex]
r = 0.059 = 5.9 %
so option B is correct
APR has he paid 5.9%
