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

### Instruction:
 Sean designs and sells patches. He orders his patches in a unit of 100 and is charged $1.25 per patch. If he turns around and sells all 100 patches for $12.00 each, what is his net profit?


### Response:
 Il commande 100 patchs et ils coûtent 1,25 $ chacun, donc les patchs coûtent 100 * 1,25 = 125,00 $.
Il facture 12,00 $ par patch et vend 100 patchs, donc il gagne 12 * 100 = 1 200,00 $.
Il a gagné 1 200,00 $ en vendant des patchs et dépense 125,00 $ pour les faire fabriquer, donc son bénéfice net est de 1 200 - 125 = 1 075,00 $.
