<human>:  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 $3000 for all the labor. How much profit did he make?
<bot>: How many planks did John make? ** He got 30*25=<<30*25=750>>750 planks
How many tables can John make? ** So he can make 750/15=<<750/15=50>>50 tables
How much money does John make? ** That means he makes 50*300=$<<50*300=15000>>15000
How much profit did John make? ** So his profit was 15000-3000=$<<15000-3000=12000>>12000
#### 12000
