Answer:
9 games
Step-by-step explanation:
If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.
This means he spent 12.5x for x number of games.
His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.
150 - (12.5x + 20) = 17.5
150 - 12.5x -20 = 17.5
130 - 12.5x = 17.5
-12.5x = 17.5 - 130
-12.5x = -112.5
x = 9
