2. In the following 2 problems, assume that all cash flows are end-of-period and the interest rates given are nominal annual rates. A. How many years will it take to triple a single deposit of $7,500 at rate of 7.9% compounded annually? (10 pts) B. Assume that you plan to buy a new car three (3) years from today and would like to pay cash for it. You found one like what you wish to own that currently costs $25,500 new; however, you know that car prices for similar types increase approximately 3% per year. Your rich Uncle Scotty Smalls says he will help out by depositing exactly $10,000 into an account today (that compounds monthly) which you may keep plus all earned interest at the end of three years to cover your purchase. If you can earn an 8% return on that account, what monthly payment should you make over the 3 years to have the exact amount you need to buy the car if you begin with your uncle's money? (20 pts)
