Question

Elisa's Bikes rents bikes for $18 plus $5 per hour. Lea paid $38 to rent a bike. For how many hours did she rent the bike?

A. 4 hours
B. 6 hours
C. 8 hours
D. 10 hours

Answer 1

Answer: 4 hours

Step-by-step explanation:

Let's make a variable so that hours = h. Using this, we can form an equation:

18 + 5h = 38 (the cost)

By subtracting 18 on both sides, we get 5h=20. Dividing 5 by both sides gets us h = 4. Therefore, Lea rented the bike for 4 hours.

Answer 2

Lea rented the bike from Elisa's Bikes for 4 hours. This was determined by subtracting the initial rental fee from the total paid and dividing the remainder by the hourly rate.

Step-by-step explanation:

The question asks us to determine the number of hours Lea rented a bike from Elisa's Bikes, knowing the rental cost structure and total amount she paid. First, we subtract the initial rental fee from the total amount to find out how much of the total was just for the hourly rate. The calculation is as follows:

$38 (total paid) - $18 (initial rental fee) = $20

Now, we divide the remaining amount by the hourly rate to find the number of hours Lea rented the bike:

$20 / $5 per hour = 4 hours

Therefore, Lea rented the bike for 4 hours, which corresponds to option A.
