Q: Michael’s largest watermelon weighs 8 pounds. His neighbor, Clay, grew a watermelon three times that size. And their mutual friend, John, grew a watermelon that was half the size of Clay’s. How big was John’s watermelon?
A: Michael’s watermelon weighs 8 pounds and Clay’s weighs 3 times that so it weighs 8 * 3 = 24 pounds. John’s watermelon is half the size of Clay’s 24 - pound watermelon so it weighs 24 / 2 = 12 pounds. The answer is 12.
Question: Laura took six trips to park. On each trip, she spent 2 hours at the park and an additinal 30 minutes walking to and from the park. What percentage of the total time she took for her trips to the park did Laura spend in the park?
Answer: During 6 days, Laura would spend 2 * 6 = 12 hours in the park. If it takes 30 minutes (or 0.5 of an hour) walking to and from the park, then for the six trips, it would take her an additional 0.5 * 6 = 3 hours to walk to and from the park. In total, she would spend a total of 12 + 3 = 15 hours on her six trips. So, the fraction of time spent in the park would be 12 / 15 = 0.8. Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park. The answer is 80.
[Question]Reese joined a Pinterest group where members contributed an average of 10 pins per day. The group owner deleted older pins at the rate of 5 pins per week per person. If the group has 20 people and the total number of pins is 1000, how many pins would be there after Reese had been a member for a month?
[Answer]In a day, the total number of new pins is 10 * 20 = 200. There will be 30 * 200 = 6000 new pins after a month. The total number with old pins present is 6000 + 1000 = 7000 pins. If the owner deletes five pins every week, the total number of deleted pins in a week is 5 * 20 = 100 pins. After a month, the number of deleted pins will be 100 * 4 = 400. The number of pins after the old pins are deleted is 7000 - 400 = 6600 pins. The answer is 6600.
Q: John Smith buys 3 cakes for $12 each and splits the cost with his brother. How much did he pay?

Question: A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
Answer: Twice the width is 4 x 2 = 8 meters. The length of the rectangular flowerbed is 8 - 1 = 7 meters. Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = 14 meters of fence. The rectangular bed has also 2 equal widths, so it needs 4 x 2 = 8 meters of fence. Therefore, the rectangular flower bed needs a total of 14 + 8 = 22 meters of fence. The answer is 22.
Q: John's camera broke so he decided to rent one for 4 weeks. It was a $5000 camera and the rental fee was 10% of the value per week. His friend who was there when it broke agreed to pay 40% of the rental fee. How much did John pay?
A:
The rental fee is 5000 * .1 = $500 per week. So it cost 500 * 4 = $2000. His friend pays 2000 * .4 = $800. So he pays 2000 - 800 = $1200. The answer is 1200.
