Your sister-in-law borrowed $5,000 from you 4 years ago and then disappeared. Yesterday she returned and expressed her desire to pay back the loan, including the interest accrued. Assuming that you had agreed to charge her 10%, and assuming that she wishes to make 8 equal annual payments beginning in one year, how much would your sister-in-law have to pay you annually in order to pay off the debt? (Assume that the loan continues to accrue interest at 10% per year.)
