Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.

To determine the expense for the arcade game and Ferris wheel, you would require information about how many times Maya played each and the total amount of money she spent from her allowance.

Sample answer: To form a two-variable equation, I would first need to find out Maya’s total allowance. Then, identify the prices for playing the arcade game and for the Ferris wheel ride. The equation could express the total cost as the sum of the cost per arcade game times the number of games plus the cost per Ferris wheel ride times the number of rides. The variables would represent how many times Maya played the arcade game and how many times she rode the Ferris wheel. This would allow solving for the number of Ferris wheel rides given the number of arcade plays.
