Answer:
15
Explanation:
You start with $50, and if $20 is spent on food then you have 50-20= $30 remaining for games.
Games are $2 each, and you have $30 for games, so we can divide the amount of money you have by the amount of money required for each game to find out how many games you can play:
30/2 = 15
Therefore after spending $20 on food, you are able to play 15 games with the remaining money.
