Answer 1

Hi Mari,

Are you trying to figure out how many games Nadeem has played? We need to know how many tokens Nadeem has remaining. This information is missing.

If we know how many tokens are remaining, then we can take the remaining tokens, subtract it from 18, and that gives us the used amount of tokens. Take the used amount of tokens and divide by 3.

For example, if Nadeem has 6 tokens remaining:

18 started - 6 remaining = 12 used.

12 used /3 per game = 4 games already played,
