Paula charges $12 to shovel a driveway. She shoveled 6 driveways on Saturday and then some more on Sunday. She made $144 for the weekend. How many driveways did she shovel on Sunday? Choose two answers: one for the equation that models this situation and one for the correct answer.

First, find the number of driveways Paula has shovelled to earn $144

$144 : $12 = 12

She has shovelled 12 driveways to earn $144.

Second, find the number of driveways she shovelled on Sunday given that she has already shovelled 6 driveways on Saturday.

12 - 6 = 6

She shovelled another 6 driveways on Sunday.

Answer: 6 driveways
