My question is: Troy bakes 2 pans of brownies, cut into 16 pieces per pan. The guests eat all of 1 pan, and 75% of the 2nd pan. One tub of ice cream provides 8 scoops. If all but 4 of the guests eat the brownies ala mode (with 2 scoops of vanilla ice cream), how many tubs of ice cream did the guests eat? Your thoughts:
Troy bakes 2 x 16 = 32 brownie pieces. 75% of one pan is 16 x 0.75 = 12 pieces. Guests eat 16 + 12 = 28 pieces. This many guests eat the brownies ala mode 28 - 4 = 24. This many scoops are eaten by the guests 24 x 2 = 48. The guests eat this many tubs 48 / 8 = 6 tubs. The final answer: 6.
