Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24 ounces. Which factorization could represent the number of water bottles and weight of each water bottle?

Factor out 12 from each term: 60x² ÷ 12 = 5x², 48x ÷ 12 = 4x, and 24 ÷ 12 = 2. Thus 60x² + 48x + 24 = 12(5x² + 4x + 2), so choice B represents 12 water bottles with each bottle weighing 5x² + 4x + 2 ounces.
