Shaylea, age$22,$ just started working$$ full$-$time and plans to deposit $$$$4$ comma $800$ annually into an IRA earning $6$ percent interest compounded annually. How much would she have in $20$years$,30$years$,$ and $40$years$?$ If she changed her investment period and instead invested $$$$400\mathrm{.}00$monthly$,$ and the investment also changed to monthly$$ compounding, how much would she have after the same three time$$ periods? Comment on the differences over time.
