Carol set up an RRSP for a client when the client was $30$ years old. The client put $$750$ into the account every month until they retired at age $60.$ The account averaged an annual rate of $7\mathrm{.}6\%$ per year compounded annually. The client then wants to take a monthly disbursement from the account starting at age $60$ for the next $25$ years. What would the monthly disbursement be if the RRSP investment retained the same terms and after $25$ years would have a zero balance?

First $30$ Years?

Next $25$ Years?
