Answer: 7 games
Step-by-step explanation:
First remove the cost of the shoe rental as this is a fixed cost:
= 20 - 1.75
= $18.25
This means that Ian had only $18.25 to spend on bowling. If each game cost $2.50, the number of games he could bowl are:
= Amount available / Amount per game
= 18.25 / 2.50
= 7.3
= 7 games
