To do this, you will make 5959 equal payments based on the 1515-year amortization schedule and then make a final 60th payment to pay the remaining balance.(Note: Be careful not to round any intermediate steps less than six decimal places.) a. What will your monthly payments be? b. What will your final payment be?
