Q: Angie bought 3 lbs. of coffee at the store today. Each lb. of coffee will brew about 40 cups of coffee. Angie drinks 3 cups of coffee every day. How many days will this coffee last her?
A: A pound of coffee makes 40 cups of coffee, so 3 lbs. coffee * 40 cups of coffee per lb. = 120 cups of coffee. Angie drinks 3 cups of coffee a day, so she has enough coffee to last her 120 cups of coffee / 3 cups of coffee per day = 40 days. The answer is 40.
Question: Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)
Answer: First find the number of ounces Erin serves per minute: 10 ounces / bowl * 5 bowls / minute = 50 ounces / minute. Then find the number of ounces in the pot: 6 gallons * 128 ounces / gallon = 768 ounces. Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces / minute = 15.36 minutes, which rounds down to 15 minutes. The answer is 15.

Q: James buys 3 dirt bikes for $150 each and 4 off-road vehicles for $300 each. It also cost him $25 to register each of these. How much did he pay for everything?
A: The dirtbikes cost 3 * 150 = $450. The off - road vehicles cost 300 * 4 = $1200. He had to register 3 + 4 = 7 vehicles. That means registration cost 25 * 7 = $175. So the total cost of everything was 450 + 1200 + 175 = $1825. The answer is 1825.
Question: James has 7 more than 4 times the number of Oreos Jordan has. If there are 52 Oreos total, how many does James have?
Answer: Let x be the number of Oreos Jordan has. James has 7 + 4x Oreos. Total: 7 + 4x + x = 52. 5x + 7 = 52. 5x = 45. x = 9. James has 7 + 4(9) = 43 Oreos. The answer is 43.
Q: After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?
A:
Since Rick and Jose's lunch cost was the same, Adam spent 2 / 3 * 45 = $30 on his lunch. The three friends ate food worth 30 + 45 + 45 = $120. The answer is 120.
