a) What is the present value of your windfall?
b) What is the future value of your windfall in three years (on the date of the last payment)?
II. Your grandfather has been putting $4000 into savings account on every birthday since your first (that is when you turned 1). The account pays an interest rate of 3%. How much money will be in the account immediately after your grandmother makes the deposit on your 18th birthday?
