An engineer borrowed $3,000 from the bank, payable in six equal end-of-year payments at 8%. The bank agreed to reduce the interest on the loan if the interest rates in the U.S. declined before the loan was fully repaid. At the end of three years, at the time of the third payment, the bank agreed to reduce the interest rate from 8% to 7% on the remaining debt. What is the equal end-of-year payments for the modified three remaining loan payments?
