For each of the next five days, Mary plans to spend 1/3 of the money she has at the beginning of the day. At the beginning of the first day, Mary has $243. Assuming that Mary doesn't get any new money over the next five days, how much money will she have after the fifth day?

243  (1/3)^5   =  243  /  243  =   $1    at  the  end of  the  5th day
