Answer:the greatest number of games that he could have played is 4
Explanation:
Let x represent the greatest number of games Elie could have played.
Total amount of money that Elie has to spend is $25. He rented shoes for $5.25 and paid $4.00 for each game. This means that if he played x games, the total amount,y that he would have spent would be
y = 5.25 + 4x
Since y = 25, then
25 = 5.25 + 4x
4x = 25 - 5.25 = 19.75
x = 19.75/4 = 4.9375
Since the number of games cannot be a fraction, the greatest number of games that he could have played is 4. He would receive a balance of 19.75 - 16 = $3.75
