Answer:
They played 3 games of bowling.
Step-by-step explanation:
Assuming each person only rents one pair of shoes, that would come out to $7.50.
Subtract this amount from the total ($55.20) and you get $47.70 leftover.
Divide the leftover amount by the price of games per person ($5.30) and you'll get nine, divide that by the number of people playing, since it's per person, and you can determine they played three games.
