Question: George is about to celebrate his 25th birthday. Since his 15th birthday, he's been given a special $1 bill from his parents. They told him that on his 25th birthday, for every bill he still has, they will give him $1.5 in exchange. He spent 20% of his special bills. How much will he receive from his parents when he exchanges them?
Answer: Step-by-step reasoning process: He received 10 special bills because 25 - 15 = 10. He has 80% of them left because 100 - 20 = 80. He has 8 left because 10 x .8 = 8. His parents will give her $12 for them because 8 x 1.5 = 12.
So the answer is 12.

Question: Charles is jogging while listening to his favorite album. He runs at 6 MPH when he's got music on and 4 MPH when he doesn't. His album is 40 minutes long. How many minutes will it take him to jog 6 miles?
Answer: Step-by-step reasoning process: He runs at .1 miles per minute because 6 / 60 = .1. While the album is playing he can run 4 miles because 40 x .1 = 4. He has to run 2 miles without the album because 6 - 4 = 2. Without music he runs 1 / 15 miles per minute because 4 / 60 = 1 / 15. He will run the remaining 2 miles in 30 minutes because 2 / (1 / 15) = 30. It will take him 70 minutes in total because 40 + 30 = 70.
So the answer is 70.

Question: Marie has 4 notebooks with 20 stamps each. She also has two binders with 50 stamps each. If she decides to only keep 1/4 of the stamps, how many stamps can she give away?
Answer: Step-by-step reasoning process: Marie has 4 x 20 = 80 stamps from her notebooks. And she has 2 x 50 = 100 stamps from her binders. So she has a total of 80 + 100 = 180 stamps. Marie decided to keep 180 x 1 / 4 = 45 stamps only. Therefore, she can give away 180 - 45 = 135 stamps.
So the answer is 135.

Question: Oliver has two bags of vegetables. Each bag weighs 1/6 as much as James's bag, which weighs 18kg. What is the combined weight of both Oliver's bags?
Answer:
Step-by-step reasoning process: Each of Oliver's bags weighs 18 kg * 1 / 6 = 3 kg. Combined, both his bags weigh 3 kg * 2 = 6 kg.
So the answer is 6.
