42. Larry Davis borrows $80,000 at 14 percent interest toward the purchase of a home. His mortgage is for 25 years.

a. How much will his annual payments be? (Although home payments are usually on a monthly basis, we shall do our analysis on an annual basis for ease of computation. We will get a reasonably accurate answer.)

b. How much interest will he pay over the life of the loan?

c. How much should he be willing to pay to get out of a 14 percent mortgage and into a 10 percent mortgage with 25 years remaining on the mortgage?
Assume current interest rates are 10 percent. Carefully consider the time value of money. Disregard taxes.
