[Question]Paul uses 1 can of frosting to frost a layer cake. He uses a half can of frosting for a single cake, or a single pan of brownies, or a dozen cupcakes. For Saturday, he needs to have 3 layer cakes, 6 dozen cupcakes, 12 single cakes and 18 pans of brownies ready and frosted for customer pick up. How many cans of frosting will he need?
[Answer]He needs 1 can of frosting per layer cake and he needs to make 3 layer cakes so that's 1 * 3 = 3 cans of frosting. There are 6 dozen cupcakes,12 single cakes and 18 pans of brownies for a total of 6 + 12 + 18 = 36 orders. Each of the 36 orders needs 1 / 2 can of frosting so they need 36 * .5 = 18 cans of frosting. He needs 3 cans of frosting for the layer cakes and 18 cans for the remaining items for a total of 3 + 18 = 21 cans of frosting. The answer is 21.

Question: Eric spent 2 hours removing wallpaper from just 1 wall of his 4 walled dining room. He also needs to remove wallpaper from his 4 walled living room. How many hours will it take him to remove the remaining wallpaper?
Answer: His dining room is 4 walls and he has already removed 1 wall of wallpaper so that leaves 4 - 1 = 3 walls in the dining room. He has 3 walls left in the dining room and 4 in his living room for a total of 3 + 4 = 7 walls. It takes 2 hours to remove wallpaper from just 1 wall and he has 7 more to go so it will take him 2 * 7 = 14 hours. The answer is 14.

Q: Jane is dividing up minnows to be carnival prizes. She bought 600 minnows, and each prize is a bowl with 3 minnows. If 800 people are going to play the game and 15% win a prize, how many minnows will be left over?
A: First find the number of people that win a prize: 800 people * 15% = 120 people. Then multiply that number by the number of minnows each person wins: 120 people * 3 minnows / person = 360 minnows. Then subtract that number of minnows won from the starting number to find the number that are left: 600 minnows - 360 minnows = 240 minnows. The answer is 240.
