The Wild West Frontier Park now offers a higher entrance fee but a lower per ride fee. For $30.00, visitors can go on each ride for only $2. The original plan charged visitors $9
to enter the park, plus $5 for each ride. Write an equation to determine the number of
rides that would make the total cost equal for the two plans. Write and solve a system
of equations to solve. After how many rides will the two plans cost the same?
