Q: Donna made a cake to take to a party where the guests ate half the cake. The day after the party, she shared half the leftovers with her brothers. The following day, she ate one piece as a midnight snack. Twice as many pieces as her snack were left. How many pieces was the cake to begin with?
A: Donna had 2 * 1 = 2 pieces of cake left. Before her snack, there were 2 + 1 = 3 pieces left. Those 3 pieces were half the leftovers, so she had 3 * 2 = 6 pieces before sharing with her brothers. Those 6 pieces were half the party leftovers, so the cake was 2 * 6 = 12 pieces before the party. The answer is 12.
Question: At the Mystic Aquarium, sharks are fed four buckets of fish each day. The dolphins are fed half as many buckets as the sharks while the other sea animals are fed five times as many buckets as the sharks. How many weeks will 546 buckets of fish last?
Answer: The dolphins are fed 4 / 2 = 2 buckets of fish each day. The sea animals are fed 4 x 5 = 20 buckets of fish each day. So, the Mystic Aquarium needs 4 + 2 + 20 = 26 buckets of fish each day. Thus in a week, it needs 26 x 7 = 182 buckets of fish. Therefore, 546 buckets of fish will last for 546 / 182 = 3 weeks. The answer is 3.
[Question]Every time she goes to the store, Felicity gets a lollipop. After she finishes them, she uses the sticks to build a fort. The fort needs 400 sticks to finish it. Her family goes to the store three times a week and she always goes. If the fort is 60% complete, how many weeks has Felicity been collecting lollipops for?
[Answer]She has 240 sticks because 400 x .6 = 240. She has been going to the store for 80 weeks because 240 / 3 = 80. The answer is 80.
Q: Michael saved 5 of his cookies to give Sarah, who saved a third of her 9 cupcakes to give to Michael. How many desserts does Sarah end up with?
A: Sarah saved 1 / 3 of her 9 cupcakes to give Michael, so she has 2 / 3 x 9 = 6 cupcakes left. Michael saves 5 of his cookies for Sarah, which she adds to her 6 cupcakes. Sarah has 5 + 6 = 11 desserts. The answer is 11.

Q: When Michelle makes fresh pasta, she first makes the dough, then she rolls it out and cuts it, and then she hangs it on racks to dry for cooking later. She needs a drying rack for each three pounds of pasta she makes, and it takes two cups of flour to make each pound of pasta dough. She owns three racks right now. How many more drying racks will Michelle need if she makes pasta using three 8-cup bags of flour?
A:
Michelle used 3 * 8 = 24 cups of flour in the pasta dough. She made 24 / 2 = 12 pounds of pasta dough. She needs 12 / 3 = 4 drying racks for the pasta. Thus, Michelle needs 4 - 3 = 1 more drying rack. The answer is 1.
