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?
Use reasoning to answer the following question.
6
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.

.

Therefore, the answer is 6
