Robert Downey deposited $610.00 in a trust account on the day of his son's birth and every three months thereafter. If Interest paid is 7.2% compounded quarterly, what will the balance in the trust account be before the deposit is made on the son's twenty-first birthday? Please show formula and work to get paid - It does not help me if you only put an answer :) (I always try to make sure I comment or select best answer as soon as you post so I can be fair with it!) Thank You so much in advance!
