You would need the times she played the arcade game, the times she rode the Ferris wheel, and the total amount of her allowance that she spent in order to find how much the arcade game and the Ferris wheel cost.
Sample Response: To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.
5 people - pay 135 each 15 people - pay x each ---------------------------------- 5 : 15 = x : 135 15 x = 5 * 135 15 x = 675 x = 675 : 15 x = 45 Answer: B ) 45.00
