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?

How many games will all his friends play? ** He needs to buy enough tokens for 240 games because 4 x 60 = <<4*60=240>>240
How many tokens will he need? ** He needs to buy 480 tokens because 2 x 240 = <<2*240=480>>480
How much will it cost? ** He needs to spend 160 because 480 / 30 = 16
