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

### Instruction:
Jeff orders a Halloween costume.  He has to put in a 10% deposit and then pay the rest when he picks it up.  The costume is 40% more expensive than last year's costume, which cost $250.  How much did he pay when picking it up, in dollars?

### Response:
 Yaligharimu 1.4 * $250 = $<<1.4*250=350>>350.
Hivyo amana ilikuwa $350 * 0.1 = $<<350*.1=35>>35.
Hivyo alilazimika kulipa $350 - $35 = $<<350-35=315>>315 alipochukua.
