A. Let x be the number of games Leo can play. The inequality to solve is:
0.75x + 4.25 ≤ 20
B. To solve the inequality:
0.75x ≤ 20 - 4.25
0.75x ≤ 15.75
x ≤ 21
Leo can play a maximum of 21 games.
C. The inequality represents the maximum amount of money Leo can spend on games and snacks, which is $20. The left side of the inequality represents the total amount of money spent on games and snacks, and it must be less than or equal to $20. We solve for x, which represents the number of games Leo can play within the $20 budget. The solution is x ≤ 21, meaning Leo can play a maximum of 21 games.
