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

### Instruction:
 Carl anataka kununua koti jipya ambalo ni ghali sana. Alipata akiba ya $25 kila wiki kwa wiki 6. Katika wiki ya saba, alilazimika kutumia theluthi moja ya akiba yake kulipa bili. Katika wiki ya nane, baba yake alimpa pesa ziada ili aweze kununua koti lake la ndoto. Ikiwa koti linagharimu $170, baba yake alimpa pesa kiasi gani?


### 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.
