George plans to deposit $1200 at the end of every 6 months for 15 years into an RRSP account. After the last deposit, he intends to convert the existing balance into an RRIF and withdraw equal amounts at the end of every 6 months for 20 years. If interest is expected to be 7.5% compounded semi-annually, how much will George be able to collect every 6 months?
