20. Jeff obtains a mortgage loan of 55,000 to be repaid with monthly pay- ments at the end of each month over n years. Each monthly payment is 500.38 based on a nominal interest rate of i> 0 compounded monthly. Jeff is unable to make the first payment but makes all the other payments on time. Still because he skipped the first payment, he owes 3077.94 at the end of n years. Calculate i.
