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?
Thoughts? Step-by-step reasoning:

He got 30 * 25 = 750 planks. So he can make 750 / 15 = 50 tables. That means he makes 50 * 300 = $15000. So his profit was 15000 - 3000 = $12000.
Thus, the answer is 12000.
