Noah and Emma are wondering how much they need to have saved on the day they retire $(30$ years from now$).$ They plan to withdraw the equivalent of $$80,000($today$\text{'}$s dollars$)$ each year that they are retired. They expect inflation to average $2\mathrm{.}5\%$ per year. $($Assume each withdrawal will be $2\mathrm{.}5\%$ larger than the prior year's withdrawal$).$ They will be retired for $20$ years. They plan on their retirement money earning a return of $8\mathrm{.}0\%$ per year during the time they are retired. How much money do they need to have on hand on the day they retire?
