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?
Use reasoning to answer the following question.
16
He needs to buy enough tokens for 240 games because 4 x 60 = 240.

He needs to buy 480 tokens because 2 x 240 = 480.

He needs to spend 160 because 480 / 30 = 16.

.

Thus, the answer is 16
