Q: A paper company decides to operate their business more sustainably. They decide that for every tree they chop down, they want to plant three more. If the company chops down 200 trees in the first half of the year and 300 more trees in the second half of the year, how many more trees does the company need to plant?
A: The company has chopped down a total of 200 + 300 = 500 trees throughout the year. They plant 3 trees for every tree they chop so they need to plant 500 trees * 3 = 1500 trees. The answer is 1500.
Question: Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days?
Answer: On Tuesday, Oliver worked out for 4 - 2 = 2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = 8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = 4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = 18 hours. The answer is 18.
[Question]Monroe made 200 granola bars for her family. She and her husband ate 80, and the rest was divided equally among her children. If each child received 20 granola bars, how many children are in the family?
[Answer]If Monroe and her husband ate 80 granola bars, then the number of granola bars the children shared is 200 - 80 = 120. Each child received 20 bars, and there were 120 granola bars, meaning there were 120 / 20 = 6 children in the family. The answer is 6.
Q: Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?
A: 5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00. The answer is 23.
Question: Jason spent 1/4 of his money and an additional $10 on some books. He then spent 2/5 of the remaining money and an additional $8 on some DVDs. If he was left with $130, how much money did he have at first?
Answer:
Let X be the money Jason had at first. Jason spent 1 / 4 * X + 10 on books. Jason spent 2 / 5 * [X - (1 / 4 * X + 10)] + 8 on some DVDs. Jason has X - (1 / 4 * X + 10) - {2 / 5 * [X - (1 / 4 * X + 10)] + 8} = $130 left. X - 1 / 4 * X - 10 - 2 / 5 * X + 1 / 10 * X + 4 - 8 = $130. 9 / 20 * X - 14 = $130. X = $320. The answer is 320.
