Question

5) You and your friend rent a tandem bike. It costs $24 for the ride and $4.50 for each extra hour. The total cost is $42. Write and solve an equation to find the number of extra hours you rented the bike.​

Answer 1

Let H be the number of extra hours you rented the bike.

The total cost of the bike rental is $24 for the ride plus $4.50 for each extra hour, so the equation is:

24 + 4.50H = 42

To solve this equation, we can subtract 24 from both sides to get:

4.50H = 42 - 24

Then we can simplify the right side to get:

4.50H = 18

Finally, we can divide both sides by 4.50 to find the number of extra hours H:

H = 18 / 4.50

H = 4

So you rented the bike for 4 extra hours.
