Bike-a-Rema rents bikes at an hourly rate of $9.00 per bike, but also charges a flat maintenance fee of $5.00.For maintenance fee, bike-a-Rama provides grease for the chain to prevent it from slipping off. What function would represent the relationship between, y, the total cost, and the numbers of hours, x?

The answer is,

y = 5 + 90x

Step-by-step explanation: Let y be the total cost of renting the bike and x would be the number of hours the bike would be rented out. There is a flat fee of $5 which means regardless of how long the bike is rented out, (either an hour or even ten hours) you must pay $5. Also for every hour you have the bike in your possession, you would pay $90 for every hour (that is 2 hours would attract a 90 x 2 charge).

However Bike-a-Rama charges both a flat fee and an hourly fee, so to rent a bike for a total of x hours, the relationship between y, the cost and x the number of hours would be expressed as follows;

y = 5 + 90x
