Answer:
2 games
Explanation:
$ 4 to rent shoes and $ 3.50 per game
4 + 3.50g
$ 7 to rent shoes and $ 2 per game
7 + 2g
when will they charge the same....when will they be equal...so set them equal to each other and solve for g, the number of games
4 + 3.50g = 7 + 2g
3.50g - 2g = 7 - 4
1.50g = 3
g = 3 / 1.50
g = 2 <===
