Clara and her brother, Carl, are at the beach for vacation. They want to rent bikes to ride up and down the boardwalk. One rental shop, Bargain Bikes, advertises rates of $5 plus $1.50 per hour. A second shop, Frugal Wheels, advertises a rate of $6 plus $1.25 an hour. How much does it cost to rent a bike for one hour from each shop? How about 10 hours?

Let's evaluate each rental shop:

Bargain Bikes: $5 plus $1.5 per hour.

For one hour, the cost is $5 + $1.5 = $6.5. For ten hours the total cost is: $5 + 10*$1.5 = $20

Frugal Wheels: $6 plus $1.5 an hour.

For one hour, the cost is $6 + $1.25 = $7.25. For ten hours the total cost is: $6 + 10*$1.25 = $18.5

If Clara and her brother are thinking about renting a bike for an hour, Bargain Bikes is the best option. On the other hand, if they want to rent it fr several hours Frugal Wheels is the best option.
