Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
He puts 10 charms on each necklace that cost $15 so each necklace cost 10*15=$<<10*15=150>>150 to make
He sells each necklace for $200 each so he makes a profit of 200-150=$<<200-150=50>>50 each
If he sells 30 necklaces, his total profit would be 30*50=$<<30*50=1500>>1500
