Final answer:
Chris could play a maximum of 6 full games of bowling after renting shoes, as he would have $20 left and each game costs $3.
Step-by-step explanation:
The student Chris went bowling with $25 to spend. After renting shoes for $5, he would have $25 - $5 = $20 remaining to spend on games. If each game costs $3, the maximum number of games Chris could play is calculated by dividing the remaining amount by the cost per game: $20 ÷ $3 = approximately 6 full games, since you cannot play a fraction of a game with a monetary transaction in this context.
