Make this into an equation. The total (20) has to be greater than or equal to the cost to rent the shoes (1.25) plus the .75 for each game. You choose ≥ for the inequality because you can't spend more than $20.
20 ≥ 1.25 + .75G
To begin solving for G, subtract the 1.25 from both sides:
18.75 ≥ .75G
Divide both sides by .75:
25 ≥ G
