Q: On Thursday the Meat Market sold 210kg of ground beef. On Friday they sold twice that amount. On Saturday they only sold 130kg. On Sunday they sold half of what they sold Saturday. If they originally planned to sell only 500kg, how much meat did they sell beyond their original plans?
A: On Friday they sold 210 × 2 = 420kg. On Sunday they sold 130 ÷ 2 = 65kg. They sold a total of 210 + 420 + 130 + 65 = 825kg of meat. Meat Market sold an extra 825 - 500 = 325kg of meat beyond their original 500kg plans. The answer is 325.
Question: John has to hire a lawyer. He pays $1000 upfront. He then gets charged $100 per hour. The lawyer has to work 50 hours in court time. It takes 2 times that long in prep time. His brother pays half the fee. How much did John pay?
Answer: The lawyer worked 50 * 2 = 100 hours out of court. So he worked 100 + 50 = 150 hours total. That means the hourly time cost 150 * 100 = $15000. Adding the upfront cost it was 15000 + 1000 = $16000. His brother paid half so he paid 16000 / 2 = $8000. The answer is 8000.
[Question]To make a cherry pie, Veronica needs 3 pounds of pitted cherries. There are 80 single cherries in one pound of cherries.  It takes 10 minutes to pit 20 cherries. How many hours will it take Veronica to pit all the cherries?
[Answer]There are 80 cherries in a pound and she needs 3 pounds to make a pie so she needs 80 * 3 = 240 cherries. It takes her 10 minutes to pit a unit of 20 cherries. She has 240 / 20 = 12 units of cherries to pit. It takes 10 minutes to pit a unit of cherries and she has 12 units so it will take her 10 * 12 = 120 minutes. 60 minutes are in 1 hour and it takes her 120 minutes so that’s 120 / 60 = 2 hours. The answer is 2.
Q: During a school meeting, 300 students and 30 teachers are seated but 25 students are standing. How many attended the school meeting?

Question: The lifespan of a hamster is 6 years less than that of a bat. The lifespan of a frog is 4 times that of a hamster. Altogether, the lifespan of the animals is 30 years. What is the lifespan of the bat?
Answer: Let’s set up an equation by calling the lifespan of a bat x, and therefore the lifespan of the hamster x – 6, and the lifespan of the frog 4 (x – 6) which add together to equal 30, like this: x + x – 6 + 4 (x – 6) = 30. That gives us 6x – 30 = 30 and we should add 30 to each side to try to isolate the x. Now we have 6x = 60, which we will divide by 6, 6x / 6 = 60 / 6. This gives us x = 10. The bat has a lifespan of 10 years. The answer is 10.
