Question

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?

Answer 1

Answer: 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

Answer 2

y = 9x + 5

With y in dollars and x in hours.

Explanation:

Bike-a-Rama charges $9 hourly for each of their bikes. And they have a fixed maintenance fee of $5.

The total cost of renting a bike, just like almost every business venture, would be given as

Total Cost = (Fixed Cost) + (Variable Cost)

Total Cost = y (the total absolute cost of renting a bike)

Fixed Cost = The compulsory maintenance cost for everyone that wants to rent = $5

Variable Cost = (Rent Rate given per hour) × (number of hours the bike is rented)

Rent rate given per hour = $9 per hour

Number of hours the Nike is rented = x

Variable Cost = $9x

Total Cost = y = 5 + 9x

So, y = $(9x + 5)

Hope this Helps!!!
