### Instruction:
 Oliver ana marafiki 4 ambao anawaalika kwenye sherehe ya michezo ya video. Vipande vya mchezo vinagharimu 30 kwa $1. Kila mchezo unagharimu vipande 2. Ikiwa anataka marafiki zake wote wacheze michezo 60 kila mmoja, itagharimu kiasi gani?


### 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
