Question

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?

Answer 1

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.
