to rent a bike for 3 hours it costs $12. for 5 hours it costs $20. a) write an equation that models the cost of a bike rental as a function of hours rented. b) how much will it cost to rent a bike for 1 hour?
To answer b - You need to find how much it costs to rent a bike per hour. To do this divide the over all cost ($12) by your amount of time (3 hrs) to get $4 per hour. Same with the $20 per 5 hours!
