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

### Instruction:
Mr. Caiden wants to do repairs to his house and requires 300 feet of metal roofing to do this. If each foot of roofing costs $8, and the supplier of the metal roofing brings in 250 feet of metal roofing for free, how much money is Mr. Caiden required to pay for the remaining metal roofing?

### Response:
 Kwa kuwa inahitajika mita 300 za bati, na mita 250 zilitolewa bure, basi mita 50 chache za bati zinahitajika.
Hii ni sawa na 50 * $8 = $400 ambayo Bwana Caiden anapaswa kulipa kwa mita ya bati iliyobaki.
