Ken and Belinda have a five-year-old daughter. At the end of every six months for the next 123 years, they wish to contribute equal amounts to a Registered Education Savings Plan (RESP). Six months after the last RESP contribution, the first of 12 semiannual withdrawals of $5100 will be made. If the RESP earns 8.6% compounded semiannually, what must be the size of their regular RESP contributions? (Do not round intermediate calculations and round your final answer to 2 decimal places.) PMT
