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

### 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:
 Soit W égal aux gains de James à la tombola.
Il a gagné W et en a donné la moitié, donc il lui restait W - W/2 = W/2.
Ensuite, il a dépensé 2 $ pour un hot-dog, donc W/2 - 2 = 55 $.
Ainsi, la moitié de ses gains est W/2 = 55 + 2 = 57.
Il a donc gagné W = 57 * 2 = 114 $.
