you play 3 games in 2.5 hours, so:


(3)/(2.5)=1.2

1.2 games is the average rate of games per hour.

To find the average cost per game, we are going to divide the total cost by the 3 games you play:


(42)/(3)=14

$14 is the average cost per game.

To find the average cost per person, we are going to divide the total cost by the 4 of you:


(42)/(4)=10.5

$10.5 is the average cost per person

To find the average cost per minute, we are going to divide the total cost by 150 minutes because is the equal to 2.5 hours:


(42)/(150)=0.28

$0.28 is the average cost per minute
