Katy, Wendi, and Carrie went to a bread-making party. Katy brought three 5-pound bags of flour. Wendi brought twice as much flour as Katy, but Carrie brought 5 pounds less than the amount of flour Wendi brought. How much more flour, in ounces, did Carrie bring than Katy?
Thoughts? Step-by-step reasoning:
Katy's three 5 - pound bags of flour weigh 3 * 5 = 15 pounds. Wendi brought twice as much flour as Katy, or 15 * 2 = 30 pounds of flour. Carrie brought 5 pounds less flour than Wendi, or 30 - 5 = 25 pounds of flour. Thus, Carrie brought 25 - 15 = 10 pounds of flour more than Katy. In ounces, the 10 pound difference is 10 * 16 = 160 ounces.
Thus, the answer is 160.
