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

### 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:
 Kila mkufu unagharimu 10*15=$<<10*15=150>>150.
Hivyo anapata faida ya 200-150=$<<200-150=50>>50.
Hivyo faida yake jumla ni 50*30=$<<50*30=1500>>1500.
