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

### Instruction:
 Oliver has 4 friends that he is inviting to a party at the arcade. Game tokens cost 30 for $1. Each game costs 2 tokens. If he wants all his friends to get to play 60 games each, how much will it cost?


### Response:
 Il doit acheter suffisamment de jetons pour 240 parties car 4 x 60 = <<4*60=240>>240.
Il doit acheter 480 jetons car 2 x 240 = <<2*240=480>>480.
Cela lui coûtera 160 $ car 480 / 30 = <<480/30=16>>16.
