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. Which equation will represent Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.

12.20h + 7.15 = E

12.20h - 7.15 = E

7.15h + 12.20 = E

7.15h - 12.20 = E
