user: Q: Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
A: If Kameron has 100 kangaroos, he has 100 - 20 = 80 more kangaroos than Bert. Buying 2 kangaroos every day, it will take Bert 80 / 2 = 40 days to have the same number of kangaroos as Kameron has now. The answer is 40.
Question: Andy has 4 times as many white socks as he has black socks. If he loses half his white socks, how many more white socks does he still have than black socks if he has 6 black socks?
Answer: Andy has 6 x 4 = 24 white socks. He loses 24 / 2 = 12 white socks. He still has 12 - 6 = 6 white socks more than black socks. The answer is 6.
[Question]James has a rainwater collection barrel. For each inch of rain he collects 15 gallons. On Monday it rained 4 inches and on Tuesday it rained 3 inches. He can sell water for $1.2 per gallon. How much money did he make from selling all the water?
[Answer]It rained 3 + 4 = 7 inches. So he collected 7 * 15 = 105 gallons. So he makes 105 * 1.2 = $126 from selling the water. The answer is 126.
Q: An airplane took a trip along the Eastern Coast of the USA. During the trip, the plane hovered in Mountain time for 3 hours, Central time for 4 hrs, and Eastern time for 2 hrs. The next day it took 2 more hours to hover in each of the places it passed through the previous day. Calculate the total time it took the plane to hover over Mountain time, Central time, and Eastern time in the two days.
A: The total time it took to hover over the Mountain and the central time is 3 + 4 = 7 hours. If it hovered further to the Eastern time zone, it took a total of 7 + 2 = 9 hours to cover the whole trip. The next day, it took 2 more hours to cover each of the places it passed through the previous day, taking a total of 2 * 3 = 6 hours. The total time it took on the second day to cover the distance it covered the previous day is 9 + 6 = 15 hours. In total, the train took 15 + 9 = 24 hours to hover over the places in the two days. The answer is 24.
Question: Caleb, Andy and Billy went on a picnic with their father. Billy took 6 candies with him, Caleb took 11 and Andy left with 9. On the way, their father bought a packet of 36 candies. He gave 8 candies to Billy, 11 to Caleb and the rest to Andy. How many more candies does Andy now have than Caleb?
Answer: Billy took some candies and got more from his father for a total of 6 + 8 = 14 candies. Caleb has a total of 11 + 11 = 22 candies. Their father gave out 8 + 11 = 19 candies from a pack of 36. He gave the rest which is 36 - 19 = 17 candies to Andy. Andy has a total of 9 + 17 = 26 candies. Andy has 26 - 22 = 4 more candies than Caleb. The answer is 4.
Q: Brian is taping up some boxes. Each box needs three pieces of tape, one as long as the long side and two as long as the short side. If Brian tapes up 5 boxes that measure 15 inches by 30 inches and 2 boxes that measure 40 inches square, how much tape does he need?
A:

assistant: First find the amount of tape each 15 in x 30 in box needs on the short sides: 2 sides * 15 inches / side = 30 inches. Then add that to the amount of tape each 15 in x 30 in box needs on the long side to find the total amount needed per box: 30 inches + 30 inches = 60 inches. Then multiply that amount by 5 boxes to find the total amount needed: 60 inches / box * 5 boxes = 300 inches. Then find the amount of tape each 40 in x 40 in box needs for its three equal length sides: 3 sides * 40 inches / side = 120 inches. Then multiply that amount by 2 boxes to find the total amount needed: 120 inches / box * 2 boxes = 240 inches. Then add the total amount needed for each box size to find the grand total: 240 inches + 300 inches = 540 inches. The answer is 540.
