Lewis wants to play several games of paintball with his friends. At the park, it costs $10.90 for admission and paintballs, and $6.18 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. y = $10.90x + $6.18 B. y = $6.18x C. y = $6.18x + $10.90 D. $10.90y = $6.18x
