Reasoning and answer: The 5 model cars cost $20 x 5 = $100. The 5 bottles of paint cost $10 x 5 = $50. The 5 paint brushes cost $2 x 5 = $10. Thus, Marc spent $100 + $50 + $10 = $160 in total.
The answer: 160

Question: Marc bought 5 model cars that cost $20 each and 5 bottles of paint that cost $10 each. He also bought 5 paintbrushes that cost $2 each. How much did Marc spend in total?
First find the total cost of the wasted meat: $5 / pound * 20 pounds = $100. Then find the total cost of the wasted vegetables: $4 / pound * 15 pounds = $60. Then find the total cost of the wasted bread products: $1.50 / pound * 60 pounds = $90. Then find the time - and - a - half rate for the janitors: $10 / hour * 1.5 = $15 / hour. Then multiply that by the number of hours to find the total janitorial cost: $15 / hour * 10 hours = $150. Then add up all the costs to find the total cost of everything: $100 + $60 + $90 + $150 = $400. Then divide the total James owes by his hourly wage to find how many hours he needs to work: $400 / $8 / hour = 50 hours.
The answer: 50
Reverse engineering the question: James started a food fight in his school's cafeteria, and the school administration is making him work off the cost of all the food he wasted at minimum wage ($8). James has to pay for 20 wasted pounds of meat at $5/pound, 15 wasted pounds of fruits and vegetables at $4/pound, 60 wasted pounds of bread products at $1.50/pound, and 10 hours of time-and-a-half pay for the janitorial staff, who normally make $10/hour. How many hours will James have to work to pay for everything?
Reasoning and answer: For 6 lemons, Tom will pay 6 * 2 = $12. For 3 papayas, he will pay 3 * 1 = $3. For 2 mangos, he will pay 2 * 4 = $8. In total, the cost of the fruits before discount is 12 + 4 + 8 = $24. The total number of fruits is 6 + 4 + 2 = 12 fruits. For 12 fruits, Tom gets a discount of 12 / 4 = $3. Subtracting the discount offered by the store, Tom will pay 24 - 3 = $21.
The answer: 21

Question: Tom went to the store to buy fruit. Lemons cost $2, papayas cost $1, and mangos cost $4. For every 4 fruits that customers buy, the store offers a $1 discount. Tom buys 6 lemons, 4 papayas, and 2 mangos. How much will he pay?
A tetris is worth 8 * 1000 = 8000 points. So he scored 4 * 8000 = 32000 points from tetrises. He also scores 6 * 1000 = 6000 points from singles. So in total he scores 32000 + 6000 = 38,000 points.
The answer: 38000
Reverse engineering the question: A single line is worth 1000 points. A tetris is worth 8 times that much. Tim scored 6 singles and 4 tetrises. How many points did he score?
Reasoning and answer: Each week, David will spend 3 hours + 3 hours + 4 hours = 10 hours in class. Add to that his 4 hours of small group work, 4 + 10 = 14 hours a week. He will spend 14 hours x 24 weeks = 336 hours on the course.
The answer: 336

Question: David is taking a data analytics course that lasts for 24 weeks. The course consists of 2 three-hour classes and 1 four-hour class each week. In addition, David must spend 4 hours each week working on small group homework assignments. How many hours will he spend on this course?
Reasoning and answer: If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old.
The answer: 72

Question:
Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years?
