1. Jim Thorpe borrows $70,000 toward the purchase of a home at 12 percent interest. His mortgage is for 30 years. a. How much will his annual and monthly payments be? 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 12 percent mortgage and into a 10 percent mortgage with 30 years remaining on the mortgage? Suggestion: Find the annual savings and then discount them back to the present at the current interest rate (10 percent). 2. Your younger sister, Brittany, will start college in five years. She has just informed your parents that she wants to go to Eastern State U., which will cost $30,000 per year for four years (cost assumed to come at the end of each year). Anticipating Brittany's ambitions, your parents started investing $5,000 per year five years ago and will continue to do so for five more years. How much more will your parents have to invest each year for the next five years to have the necessary funds for Brittany's education? Use 10 percent as the appropriate interest rate throughout this problem (for discounting or compounding). Round all values to whole numbers
