11. Each week Leslie earns $1.25 each time she walks the dog. If Leslie wants to earn $17.50 each week, which equation will determine the number of times Leslie should walk the dog in order to reach her goal of $17.50?

1.25w = 17.50

17.50 – w = 1.25

1.25 + w = 17.50

1.25w – 17.50 = 0

1. 1.25w = 17.502. 17.50 – w = 1.253. 1.25 + w = 17.504. 1.25w – 17.50 = 0
