Calculates annual interest rate.

Part 3. Using the calculated interest rate (6.75%), assume that you sell the car after 2 years. What balance will you still owe? In other words, what is the future balance in 2 years?

Note that the interest rate, I, from part 2 is not zero, so you won't get a # & error when you calculate the new I.
