Hi, can anyone show me how to do this problem? 100 points for this. in advance

James is playing his favorite game at the arcade. after playing the game 33 times, he has 88 tokens remaining. he initially had 2020 tokens, and the game costs the same number of tokens each time. the number tt of tokens james has is a function of gg, the number of games he plays

I’m still confused on how to work the percentages
