[Question]Tommy has a flag that is 5 feet wide and 4 feet tall. He wants to paint it with a new design. He knows from experience that he needs to paint both sides. Paint costs $2 a quart and a quart is good for 4 square feet. How much does he spend on paint?
[Answer]Each side of the flag is 20 square feet because 5 x 4 = 20. Both side total to 40 square feet because 2 x 20 = 40. He will need 10 quarts because 40 / 4 = 10. This will cost $20 because 10 x 2 = 20. The answer is 20.
Q: Ben makes a sandwich that has 1250 calories total that has two strips of bacon with 125 calories each. What percentage of the sandwich's total calories come from bacon?
A: First find the total number of calories in the bacon: 125 calories + 125 calories = 250 calories. Then divide the number of bacon calories by the total number of calories and multiply by 100% to express the answer as a percentage: 250 calories / 1250 calories * 100% = 20%. The answer is 20.
Question: A farmer is checking his fields to make sure all of his crops are growing as they should. Rows of corn stalks should produce 9 corn cobs each, and rows of potatoes should produce 30 potatoes each. As he’s checking crop quality, he notices that there are more pests than usual and they have destroyed some of his crops. He thinks that half of his crops have been destroyed by the pests. If the farmer has 10 rows of corn stalks and 5 rows of potatoes, how many crops does the farmer still have?
Answer: The farmer had a total of 10 rows of corn stalks * 9 corn cobs each = 90 corn cobs. He also had a total of 5 rows of potatoes * 30 potatoes each = 150 potatoes. This was a total of 90 corn cobs + 150 potatoes = 240 crops. Because pests destroyed half of his crops, he now has 240 crops * 0.5 = 120 crops. The answer is 120.
[Question]A coal-powered train is traveling towards a faraway city when the conductor realizes that he forgot to restock the train's coal supply at the last station. The train is traveling on a one-way track, so the conductor has no other option but to continue moving forward towards the city. The train can travel 5 miles for every 2 pounds of coal that it consumes. If the train has 160 pounds of coal remaining, how far can the train travel before it runs out of fuel?
[Answer]The train travels 5 miles per every 2 pounds, or 5 / 2 = 2.5 miles per pound of coal. Therefore, the 160 pounds of coal that remain are enough for the train to travel 160 * 2.5 = 400 miles. The answer is 400.
Q: The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got. If the mayor paid the two a total of $50,000, how much did Diego get?
A: Let d be Diego’s payment. Both artists were paid (1000 + 4 * d ) + d = 50000 dollars. This means that 5d = (50000 - 1000) dollars. Therefore Diego was paid d = 49000 / 5 = 9800 dollars. The answer is 9800.

Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616. The answer is 616.
