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

### Instruction:
 Ursula bought five hot dogs at $1.50 each and three salads at $2.50 each. If she had two $10 bills, how much change did she get back?


### Response:
 Cinq hot-dogs coûtent 5 x 1,50 $ = 7,50 $.
Trois salades coûtent 3 x 2,50 $ = 7,50 $.
Le montant total que Ursula devait payer était de 7,50 $ + 7,50 $ = 15 $.
Et le montant total qu'elle a reçu de ses deux billets de 10 $ était de 2 x 10 $ = 20 $.
Ainsi, Ursula a reçu un rendu de monnaie de 20 $ - 15 $ = 5 $.
