Ryan started with 36 tokens at the arcade. Ryan wasted a third of his tokens on Pac-Man, a fourth of his tokens on Candy Crush, and 7 on Ski-ball. Then, his parents bought him seven times as many tokens as he spent on Ski-ball. How many tokens did Ryan end up with? Let's think first. Chain of thought:
Ryan used 36 / 3 = 12 tokens on Pac - Man. Ryan used 36 / 4 = 9 tokens on Candy Crush. Ryan used a total of 12 + 9 + 7 = 28 tokens on all three games. Ryan had 36 - 28 = 8 tokens left. Ryan’s parents bought him 2 * 7 = 14 more tokens. Ryan had 8 + 14 = 22 tokens after his parents bought him some.
Therefore, the answer is 22.
