a)Suppose you put aside, using a bank deposit, $15,000 and leave it in the bank for n = 10 years. Exactly one year later, you start withdrawing and will make four withdrawals, the first in year n + 1, followed by three more withdrawals. During this entire period the bank pays 3.5% interest. If you want to make four equal withdrawals, leaving no money in the bank, how much is each withdrawal? Answer to the nearest cent.
