Answer:
Monthly payment = $769.27
Explanation:
First we have to determine the future value of the ordinary annuity:
Payment = $235.15
N = 20 * 12 = 240
Rate = 3.2% / 12 = 0.267%
Using a financial calculator and the FV function, the FV = $78,910.41
Again, using the financial calculator or Excel, you can determine the monthly payment:
N = 10 / 12 = 120
Rate = 0.267%
PV = $78,910.41
FV = $0
Monthly payment = $769.27
