Michael borrows 7500 dollars today, and agrees to repay the loan by making annual interest payments to the lender, and by also accumulating a sinking fund with increasing annual deposits to repay the principal. The interest rate on the loan is 9.1 percent, and the interest paid on the sinking fund is 5.6 percent, both effective. If the loan is to be settled 20 years from now, and the sinking fund deposits increase by 8 dollars per year, what is Michael's total outlay at the end of the 7th year? (Assume the first interest payment and sinking fund deposit are both due in one year.)
