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

### Instruction:
 Benny is baking pies for a bake sale. He plans to make ten pumpkin pies, which cost $3 each to make, and twelve cherry pies, which cost $5 each to make. If he wants to make a profit of $20 selling all the pies, how much does he have to charge for each pie if both kinds sell at the same price?


### Response:
 Il coûte 3 $ x 10 = 30 $ pour faire les tartes à la citrouille.
Il coûte 5 $ x 12 = 60 $ pour faire les tartes aux cerises.
Il veut faire un bénéfice de 20 $, donc il doit gagner 30 $ + 60 $ + 20 $ = 110 $ en vendant toutes les tartes.
Il fait 22 tartes, donc il doit facturer 110 $ / 22 = 5 $ par tarte.
