You anticipate that you will need $4,000,000 when you retire 40 years from now. You plan to make 40 deposits, beginning today, in a bank account that will pay 7% interest, compounded annually. You expect to receive annual raises of 2%, so you will increase the amount you deposit each year by 2%. (That is, your 2nd deposit will be 2% greater than your first, the 3rd will be 2% greater than the 2nd, etc.) How much must your 1st deposit be if you are to meet your goal? (show your work, excel)
