Final answer:
Stefan can play a maximum of 3 games with the $20 he brought.
Step-by-step explanation:
To calculate the number of games Stefan can play, we first need to subtract the cost of renting shoes from the total amount of money he brought. $20 - $5 = $15. This remaining amount represents the maximum he can spend on games.
Now, we divide the remaining amount by the cost per game to find out how many games he can play. $15 / $4.50 = 3.333. Since we can't play a fraction of a game, Stefan can play a maximum of 3 games.
The student wants to know how many games Stefan can play with the $20 he has, considering the cost of each game and the shoe rental fee. First, we need to subtract the shoe rental fee from the total amount of money Stefan has. So, we take the $20 and subtract the shoe rental fee of $5, leaving Stefan with $15 to spend on games.
Next, we divide the remaining money by the cost of each game to find out how many games he can play. The cost of each game is $4.50. When we divide $15 by $4.50, we get the number of games Stefan can play.
Performing the division, $15 ÷ $4.50 equals exactly 3 games. Thus, Stefan can play 3 full games of bowling with the $20 he brought to the bowling alley.
