Q: Bill's roof can bear 500 pounds of weight. If 100 leaves fall on his roof every day, and 1000 leaves weighs 1 pound, how many days will it take for his roof to collapse?
A: First, find how many leaves the roof can hold: 500 pounds * 1000 leaves / pound = 500000 leaves. Then divide that by the number of leaves that fall each day to find how many days before the roof collapses: 500000 leaves / 100 leaves / day = 5000 days. The answer is 5000.

[Answer]If 1 bag has 20 cookies and a box has 4 bags, then in total there are 20 * 4 = 80 cookies inside the box. If 1 cookie has 20 calories and there are 80 cookies in the box, then the box has in total 20 * 80 = 1600 calories. The answer is 1600.
Q: 3000 bees hatch from the queen's eggs every day. If a queen loses 900 bees every day, how many total bees are in the hive (including the queen) at the end of 7 days if at the beginning the queen had 12500 bees?
A: 3000 new bees are born every day. In 7 days there will be 3000 * 7 = 21000 new bees. If each day the queen loses 900 bees, in 7 days there will be 900 * 7 = 6300 fewer bees. If at the beginning the queen had 12500 bees, then at the end of 7 days she will have 12500 + 21000 - 6300 = 27200 bees. The total number of bees in the hive including the queen is 27200 + 1 = 27201. The answer is 27201.
Question: Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?
Answer: If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows. Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = 6,600 feet. He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot. 13,200 seconds is 13,2000 / 60 = 220 minutes. The answer is 220.
Q: Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil's cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?
A:
Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies. The answer is 2.
