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:
 Marafiki zake watacheza jumla ya michezo 4*60=<<4*60=240>>240
Hii itagharimu Oliver vipande 240*2=<<240*2=480>>480
Hii pia itagharimu Oliver $480/30=$<<480/30=16>>16
