John is performing in 3 plays.  Each play has 5 Acts.  He wears 2 wigs per act.  Each wig cost $5.  He drops one of the plays and sells all of the wigs for that play for $4.  How much money did he spend?
He used 5*2=<<5*2=10>>10 wigs per play
So in total, he used 10*3=<<10*3=30>>30 wigs
They cost 30*5=$<<30*5=150>>150
He gets back 10*4=$<<10*4=40>>40 from selling the wigs
So he spent 150-40=$<<150-40=110>>110
