Bonnie has borrowed 4400 dollars at a nominal rate of interest of 6.9 percent convertible monthly. She has agreed to repay the loan with 24 equal monthly payments, the first coming one month after the loan is made. After making the 9th payment, she makes a deal with the lender where she'll pay off the balance owed on the loan with 20 more monthly payments, each 1.4 percent larger than the last. The lender agrees, provided that the yield rate on the remaining payments is 9.2 percent convertible monthly. Under these new terms, how much is her last payment?
Answer = dollars.
