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

### Instruction:
James buys a weight vest for $250.  He then buys 200 pounds of weight plates for $1.2 per pound.  A 200-pound weight vest would cost $700 but there is a $100 discount.  How much does he save with his vest?

### Response:
 Ameununua sahani za uzito za 200*1.2=$<<200*1.2=240>>240
Kifuko chake kinagharimu $250+$240=$<<250+240=490>>490
Angepata kifuko kingine kwa $700-$100=$600
Hivyo amesave $600-$490=$<<600-490=110>>110
