Nadav plans on going to the amusement park this Friday. It costs $25.00 to enter the park, and then $1.25 for every ride that Nadav goes on. Which answer choice is an equation that shows the relationship between rides, r, and the total cost c?

(c, 0) i might be wrong so don't put full faith on my answer

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

combine all like terms then its just a 2 step equation
