Fred Flintstone bought seven boxes to put with his collection of boxes. A week later half the
boxes were ruined in the rain. There are now only 22 boxes left. With how many did he start?
What equation can I use to solve this?
There are 22 left ( a result of being halved ) which means there must have been 44 just before that. And, he added 7 boxes to get that 44 total. So, what is 7 less than 44?
