Fourteen years ago, Mr$.$ Lawton rolled a $$35,000$ retiring

allowance into an RRSP that subsequently earned $11\mathrm{.}8\%$ compounded

semiannually. Five years ago he transferred the funds to an RRIF.

Since then, he has been withdrawing $$2800$ at the end of each

quarter. If the RRIF earns $9\mathrm{.}8\%$ compounded quarterly, how much

longer can the withdrawals continue? $($Do not round intermediate

calculations and round up the number of payments, n$,$ to the next

whole number.$)\_\_\_\_\_\_\_\_\_$ years and $\_\_\_\_\_\_\_\_$ months.
