part a:

You are thinking about buying a new car. The sticker price is $29,000 and you have $5,000 to put towards the down payment. If you can negotiate an annual interest rate of 6 percent APR (with monthly compounding) and wish to pay for the car over a 5-year period, what would be your monthly payment?

part b:Suppose you plan to retire in 40 years. If you make 10 annual investments of $ 2,000 into your retirement account for the first 10 years, and no more contributions to the account for the remaining 30 years. If the retirement account earns a fixed 11% annual interest, how much will you have at your retirement? Round it to two decimal placeswithout the $ sign, e.g., 1234567.89.
