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

### Instruction:
James won a money prize at a charity raffle. He donated half of his winnings back to the charity, then spent $2 on a hot dog to celebrate his win. He had $55 left over. How many dollars did he win?

### Response:
 Ongeza gharama ya hotdog kwa kiasi alichotoa ili kupata jumla ya kiasi alichotumia: $2 + $55 = $<<2+55=57>>57
Kwa kuwa nusu ya ushindi wake ni $57, basi James alishinda $57 * 2 = $<<57*2=114>>114 katika bahati nasibu.
