Answer:
interest rate is 38.68 %
Step-by-step explanation:
Given data
installment = $60
time = 36 months = 36/12 = 3 years
principal = $1000
to find out
interest rate
Solution
we know student pay $60 for 36 months
so he pay total = 60 × 36 = 2160
total amount pay by student = $ 2160
so we can find interest rate by given formula
rate = (1/time)(amount/Principal - 1)
put the value time amount and principal here
rate = (1/3)(2160/1000 - 1)
rate = 0.386667
interest rate is 38.68 %
