A 20-year, $200,000 loan at a nominal annual interest rate of 12% convertible monthly is being paid off via the sinking fund method. The nominal annual interest rate earned on the sinking fund is 9% convertible monthly. Level sinking fund deposits and loan interest payments are each made at the end of each month. What is the net amount of interest paid during the 48th month of the loan? (Net interest during a given month is the amount of interest paid on the loan, minus the amount of interest earned on the sinking fund, during that month.)
