Answer:
Nominal Annual interest rate is 66% ( assuming interest paid is simple interest )
Explanation:
Amount of loan = $1,300
Repayment value = $1,371.50
Period = 1 month
Interest payment = Repayment value - Amount of loan
Interest payment = $1,371.50 - $1,300 = $71.50
Rate of interest payment = Interest payment / loan amount = $71.5 / $1,300 = 0.055 = 5.5% per month
Yearly interest = 5.5% x 12 = 66%
