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

### Instruction:
 Justin bought some jerseys. He bought four long-sleeved ones that cost $15 each, and some striped ones that cost $10 each. How many striped jerseys did Justin buy if he spent a total of $80?


### Response:
 4 maillots à manches longues coûtent 4 * 15 = 60 dollars.
Étant donné que Justin a dépensé 80 dollars au total, il a dépensé 80 $ - 60 $ = 20 dollars pour les maillots rayés.
Il y a 20 / 10 = 2 maillots rayés.
