Question

ewis wants to play several games of paintball with his friends. At the park, it costs $13.38 for admission and paintballs, and $5.61 for each game he plays. Which of the following equations could be used to determine Lewis's total cost for several games of paintball?

(Let x represent the number of games Lewis plays and y represent his total cost.)

A. 

$13.38y = $5.61x

 B. 

y = $13.38x + $5.61

 C. 

y = $5.61x + $13.38

 D. 

y = $5.61x

Answer 1

The $13.38 doesn't change, no matter how many games Ewis plays. So it's a fixed charge. If Ewis plays one game he pays $13.18 + $5.61. If he plays two games, he pays $13.38 +· $5.61•2. If he plays 3 games he pays $13.38 + $5.61•3 So it's the $5.61 that gets multiplied by the number of games played, so the equation is:

y = $5.61x + $13.38
