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

### Instruction:
 Mike wants to be the best goalkeeper on his soccer team. He practices for 3 hours every weekday, on Saturdays he practices for 5 hours, and he takes Sundays off. How many hours will he practice from now until the next game, if his team has a game in 3 weeks?


### Response:
 Mike pratique les jours de semaine pendant 3 heures/jour x 5 jours = <<3*5=15>>15 heures au total.
Ensuite, chaque semaine, il pratiquerait 15 heures + 5 heures = <<15+5=20>>20 heures au total.
Il prendrait ensuite 1 semaine x 7 jours = <<1*7=7>>7 jours de congé au total.
Donc, en 3 semaines, il pratiquerait 20 heures/semaine x 3 semaines = <<20*3=60>>60 heures au total.
