A loan officer states, “Thousands of dollars can be saved by switching to a 15?year

mortgage from a 30?year mortgage.” Calculate the difference in payments on a 30?year

mortgage at 9% interest versus a 15?year mortgage with 8.5% interest. Both mortgages are

for $100,000 and have monthly payments. What is the difference in total dollars that will

be paid to the lender under each loan?
