HI there! So Craig has $25 to spend. The rented shoes for $5.25 is the fixed price. $4 is paid for each game. An inequality for this statement is this:
5.25 + 4g ≤ 25
This is because you have no more than $25 to spend and you pay $4 per game, with $5.25 being the fixed price. First, subtract 5.25 from both sides in order to get 4g ≤ 19.75. Now, divide each side by 4 to isolate the variable "g". 19.75/4 is 4.9375. He doesn't have enough money for 5 games, so the greatest number of games Craig can play is 4.
