The Wild West Frontier Park now offers an unlimited day pass. For $29.00, visitors can go on as many rides as they want. The original plan charged visitors $8.75 to enter the park, plus $2.25 for each ride. How many rides would make the total cost equal for teh two plans?
Let y = total money
Let x = number of rides
Write the equation, in y = mx + b form, for the new plan they are now offering. Do not use $ in your equation.

Solve the system of equations to find how many rides it will take for the two plans to cost the same.
29 = 2.25r + 8.75
Write the number of rides for your answer.
