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?

welshfella · Answer

In the last problem you have 2 unknowns . You can form an equation with 2 variables  which represent the number of rides and number of games she played , but you would need to know the total of games + rides also.

welshfella · Answer

You could not find the valu of the variables from  this one equtaion.  One equation with 2 variables will have a number of solutions. You would need to know some other information  before you could find  the 2 values - such as the cost of the game and the ride  and the total amount spent.

welshfella · Answer

- that is Maya's allowance.

welshfella · Answer

for the first question you can form the equation
4.95a + 6.55b = 27.95

You can solve this by trial and error because you know that a and b must be positive whole numbers.
