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

### Instruction:
 Billy ana $25 chini ya mara mbili ya pesa aliyonayo Sam. Ikiwa Sam ana $75, wana pesa kiasi gani pamoja?


### Response:
 Billy ana $25 chini ya mara mbili ya pesa za Sam, au 2 * $75 - $25 = $150 - $25 = $<<2*75-25=125>>125.
Wana $75 + $125 = $<<75+125=200>>200 pamoja.
