Assume that Eileen Arnold from Syracuse, New York, borrows $1,700 for five years at 6% add-on interest to be repaid in monthly installments. Use the add-on equation I = PRT, to calculate Eileen's finance charge in dollars: $ Now add the interest in dollars to the original amount borrowed (the principal). The total amount that Eileen must repay is $ Divide the total amount owed by the number of monthly payments (60 payments) to obtain Eileen's monthly payment. (Round the payment to the nearest penny.) Eileen must make 60 monthly payments of $ each.
