Paying Off Student Loans Suppose that after graduation that Sarah must pay back $80,000 in student loans and that she has 15 years to do so. She has a direct subsidized undergraduate loan with an interest rate of 4.29%, compounded monthly and this interest starts to accrue the month after she graduates. The terms of her loan are such that she will make a payment at the beginning of each month for 15 years, starting with the month she graduates. Thus, she will make a total of 15 12 180 payments. Problem 11: The following will guide you through caleulating what Sarah will pay each month. Note that this can be treated analogously to the Credit Card Debt example Make sure you adapt the formula used there! A.
