Final answer:
The amount repaid for this loan is $278,820. The total interest is 28.27% of the total. The average amount per payment for interest is $219.50.
Step-by-step explanation:
A.
The amount repaid for this loan can be calculated by adding the total interest to the loan amount. $200,000 + $78,820 = $278,820.
B.
To find the percentage of the total that is total interest, divide the total interest by the amount repaid and multiply by 100. ($78,820 / $278,820) * 100 = 28.27%.
C.
The average amount per payment for interest can be calculated by dividing the total interest by the number of payments. $78,820 / 360 = $219.50 per payment.
