Every day 10% of the liquid present in the morning in Kyle's open container will evaporate. At the end of three days, what percent of the original amount of liquid remains in Kyle's container? Express your answer to the nearest tenth.

If 10%  evaporates  each day.....then  90%  of the previous day's amount remain

 

So

 

(.90)^3   = .729  = 72.9%    of the original amount remains after 3 days
