Marla wants to rent a bike Green Lake Park has an entrance fee of $8 and charges $2 per hour for bike Oak Park has an entrance fee of $2 and charges $5 per hour for bike rentals she wants to know how many hours are friend will make the costs equal

Green Lake Park: Set up the cost function C(h) where h is the number of hours
C(h) = Hourly Rental Rate * h + Entrance Fee
C(h) = 2h + 8

Oak Park: Set up the cost function C(h) where h is the number of hours
C(h) = Hourly Rental Rate * h + Entrance Fee
C(h) = 5h + 2

Marla wants to know how many hours make the cost equal, so we set Green Lake Park's cost function equal to Oak Parks's cost function:
2h + 8 = 5h + 2

To solve for h, we type this equation into our search engine and we get:
h = 2
