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

### Instruction:
 Kyle bikes for 2 hours to work every day. Ten times the time he takes to travel to work and back is the same as the cost of buying a pack of snacks (in dollars). How much will Ryan pay, in dollars, to buy 50 packs of snacks?


### Response:
 Si Kyle fait du vélo pendant 2 heures pour aller travailler et revenir, il met 2*2 = <<2*2=4>>4 heures au total.
Le coût d'achat d'un paquet de snacks, dix fois le temps que Kyle met pour se rendre au travail et revenir, est de 10*4 = 40 $.
Pour acheter 50 paquets de snacks, Ryan devra payer 50 * 40 $ = 2000 $.
