Answer:

Step-by-step explanation:

carnival A : $ 6 dollar admission and $ 1.50 per ride

A(x) = 1.5x + 6

carnival B : $ 2.50 admission and $ 2 per ride

B(x) = 2x + 2.5

how many rides can Marnie go on so that the total cost of attending both is the same...

1.5x + 6 = 2x + 2.5

6 - 2.5 = 2x - 1.5x

3.5 = 0.5x

3.5 / 0.5 = x

7 = x <=== she would have to go on 7 rides for them to both cost the same
