Question

Wilbur’s bikes rents bikes for $17 plus$2 per hour. Ashley paid $27 to rent a bike. For how many hours did she rent a bike? We need to find an equation with a variable?

Answer 1

Hello!

OK, so first we need to see all of our info.

To rent a bike = $17

Each additional hour = $2 per hour

Let "rent a bike" = r
Let "each additional hour" = h

27 = r + 2h


Now to solve.

27 - 17 = 10
10 ÷ 2 = 5

This shows us that she rented the bike for 5 hours.

Check:

27 =? 17 + 2(5)

Solve:

27 = 17 + 10
27 = 27

Yes, we are correct!

Final equation = 27 = r + 2h
Final answer = Ashely rents the bike for 5 hours.

Hope this helped!
