From the information given,
Principal = 7640
Number of years = 4
Recall, 1 year = 12 months
4 years = 4 * 12 = 48 months
rate = 5.27/100 = 0.0527
The amount of the principal to be paid each month = 7640/48 = 159.17
Amount of interest owed each month = (7640 * 0.0527)/12 = 33.55
Amount required to be paid by the borrower each month = 159.17 + 33.55 = 192.72
Total interest to be paid on the loan = 7640 * 0.0527 * 4 = 1610.51
The first answer is $1610.51
The second answer is $33.55
