John chops down 30 trees.  From each tree, he can make 25 planks.  A table takes 15 planks to make and sells for $300.  He paid $3000 for all the labor.  How much profit did he make?
He got 30*25=<<30*25=750>>750 planks
So he can make 750/15=<<750/15=50>>50 tables
That means he makes 50*300=$<<50*300=15000>>15000
So his profit was 15000-3000=$<<15000-3000=12000>>12000
