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

### Instruction:
Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks.  On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him?

### Response:
 Carl alipata akiba ya $25/kila wiki x wiki 6 = $<<25*6=150>>150.
Katika wiki ya saba, alilazimika kulipa bili $150/3 = $<<150/3=50>>50.
Akiba yake ilikuwa $150 - $50 = $<<150-50=100>>100.
Baba yake alimpa $170 - $100 = $<<70=70>>70.
