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?

From the information we have now we could write this equation:

ax+by=z

where

a - number of times she played arcade

x - prize of arcade

b - number of times of Ferris wheel

y - prize of Ferris

z - the whole allowance

so in order to make it a two-variable equasion we need to know the value of three more variables.

If let's say we know a, b, and z we could solve the problem of how much cheaper/more expensive the arcade is than ferris wheel (we could find something like x=2y, for example (we don't know yet, we need more variables) so we'd know that one game is more expensive than the other.
