in $20$ years. At that time, she can withdraw $$18,500$ per month.$$If the trust fund is invested at a $3\mathrm{.}5$ percent rate, how many

months will it last your client once she starts to withdraw the

money?$($Do not round intermediate calculations and

round your final answer to $2$ decimal places.$)$
