12(6) + 12x = 144
72 + 12x = 144
12x = 144 - 72
12x = 72
x = 72/12
x = 6...she shoveled 6 more driveways on Sunday
72 + 12x = 144
12x = 144 - 72
12x = 72
x = 72/12
x = 6...she shoveled 6 more driveways on Sunday
Answer: Hello mate!
We know that Paula charges $12 to shovel a driveway, and in Saturday she shoveled 6 driveaways, so in Saturday she wins:
$12*6 = $72
We know that she wins $144 at the weekend, so we want to know how many driveaways she shoveled in Sunday.
First, let's see how much money she did make on Sunday, this is:
$144 - $72 = $72
now, knowing that she charges $12 per driveaway, we have:
$72/$12 = 6
so she shoveled 6 driveaways in Sunday.
