Harry has two options. Option A, deposit a big amount of money now and withdraw it after 18 years. Option B, deposit a small amount of money at the end of every month for 18 years. (a) For option A, how much does he need to deposit now? (b) How much total interest will he receive for option A? (c) For option B, what is his monthly payment? (d) How much total interest will he receive for option B?
