John plays a game for 4 hours a day every day for 2 weeks.  After all that time, he is only 40% done.  He increased his playtime to 7 hours a day.  How long until he finishes the game?
There are 7*2=<<7*2=14>>14 days in two weeks
So he played 14*4=<<14*4=56>>56 hours
That means the total length of the game is 56/.4=<<56/.4=140>>140 hours
So he has 140-56=<<140-56=84>>84 hours to beat the game
So it will take him 84/7=<<84/7=12>>12 days to beat the game
