The answers are B and C. If Paula earns $12 per driveway, then she earns 12 * 6 dollars on Saturday and 12 * x dollars on Sunday. Turn the word problem into an equation: (12 * 6) + (12 * x) = 144 Factor out the $12: 12(6 + x) = 144 This equation is identical to the third answer, so one answer is C. Now solve for x, the number of driveways: 12(6 + x) = 144 [12(6 + x)]12 = 14412 6 + x = 12 6 + x - 6 = 12 - 6 x = 6. Since the number of driveways is 6, the second answer is B.
