Aya spent her allowance on playing an arcade game a few times and riding the ferris wheel more than once. write about what additional information you would need to create a two-variable equation for the scenario. what kind of problem could you solve with your equation?

You would need to know how much the arcade game cost and how much the Ferris wheel cost then let x represent the amount of times she played the arcade game and let y represent how many times she rode the ferris wheel. 
once given the x and y you could figure out how much money she spent all together.
