Tim decides to start selling necklaces he makes. He uses 10 charms to make each necklace. Each charm cost $15. He sells the necklace for $200. How much profit does he make if he sells 30? Let's think first. Chain of thought:
Each necklace cost 10 * 15 = $150 to make. So he makes a profit of 200 - 150 = $50 each. So his total profit is 50 * 30 = $1500.
Therefore, the answer is 1500.
