Answer:
5.27%
Step-by-step explanation:
APR = {[(interest / principal)/n] x 365 days} x 100
- total payments = 60 x $615 = $36,900
- interests paid = $36,900 - $29,200 = $7,700
- principal = $29,200
- n = 5 years x 365 days = 1,825 days
APR = {[($7,700 / $29,200) / 1,825 days] x 365 days} x 100
APR = {(0.26369863 / 1,825 days) x 365 days} x 100 = 5.27%
