Q: Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for?
A: The silver has a volume of 3 * 3 * 3 = 27 cubic inches. So it weighs 27 * 6 = 162 ounces. So its value is 162 * 25 = $4050. That means he sold it for 4050 * 1.1 = $4455. The answer is 4455.
Question: At its current growth rate, a certain plant will be 80 feet tall after a year. If the plant grows at the same rate every month and is currently 20 feet tall, what's its monthly growth rate in feet?
Answer: If the plant is currently 20 feet tall, it will have grown by 80 - 20 = 60 feet after a year. Since a year has 12 months, and the tree grows at the same rate every month, the tree grows at 60 / 12 = 5 feet every month. The answer is 5.
[Question]Cody has an insurance plan that will give him a discount if he logs a total of 100,000 steps. For the first week, he logs 1,000 steps a day. He increases his daily number of steps by 1,000 every week. After 4 weeks how far away from his step goal will he be?
[Answer]For the first week, Cody will log a total of 7 * 1,000 = 7,000 steps. For the second week, Cody will log a total of 7 * 2,000 = 14,000 steps. For the third week, Cody will log a total of 7 * 3,000 = 21,000 steps. For the fourth week, Cody will log a total of 7 * 4,000 = 28,000 steps. For the month, Cody will log a total of 7,000 + 14,000 + 21,000 + 28,000 = 70,000 steps. This means, Cody will be 100,000 - 70,000 = 30,000 steps short of his goal. The answer is 30000.
Q: John starts climbing a very steep hill. He travels 1 foot vertically for every two feet horizontally. His elevation increases from 100 feet to 1450 feet. How far does he move horizontally, in feet?

Q: Sarah decided to pull weeds from her garden. On Tuesday she pulled 25 weeds. The next day she pulled three times the number of weeds she did the day before. On Thursday her allergies bothered her and she could only pull up one-fifth of the weeds she pulled on the day before. Finally, on Friday it rained for half the day and she managed to pull up 10 fewer weeds than she did on Thursday. In total, how many weeds did she pull up?
A:
On Wednesday she pulled 25 * 3 = 75 weeds. On Thursday she pulled 75 / 5 = 15 weeds. On Friday she pulled 15 - 10 = 5 weeds. In total she pulled 25 + 75 + 15 + 5 = 120 weeds. The answer is 120.
