Maya 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 could include money or time in this. E.g. it takes 15 minute for the Ferris Wheel to go round once and 2 minutes per arcade game. At how many goes of playing will the two reach the same time?
