- Katie Akesson
Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare. Write an equation that represents Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.
One day, Jada takes home $90.45 after working h hours and after paying the bus fare. Write an equation to represent this situation.
Is 4 a solution to the last equation you wrote? What about 7?
In this situation, what does the solution to the equation tell us?
