Question: Bart fills out surveys to earn money. He receives $0.2 for every question he answers in the survey. Each survey has 10 questions. On Monday he finished 3 surveys, and on Tuesday 4 surveys. How much money did he earn during these two days?
Answer: On Monday and Tuesday Bart finished 3 + 4 = 7 surveys. Each survey has 10 questions, so he answered 10 * 7 = 70 questions. Bart gets paid $0.2 for each questions, so he earned 70 * $0.2 = $14. The answer is 14.

Question: A firefighter's hose can deliver 20 gallons of water per minute. For a building fire that requires 4000 gallons of water to put out, how long will it take, in minutes, for a team of 5 firefighters, each with their own hose, to put out the fire?
Answer: A team of 5 firefighters with hoses can deliver 5 * 20 = 100 gallons of water per minute. To deliver 4000 gallons, this team will take 4000 / 100 = 40 minutes to extinguish the fire. The answer is 40.

Question: Allie, Rob, and Allyn each bought a bowl of grapes. Allie's bowl contained two more grapes than Rob's bowl. Allyn's bowl contained four more grapes than Allie's bowl. If Rob's bowl contained 25 grapes, what is the total combined number of grapes in all three bowls?
Answer: If Allie's bowl contained two more grapes than Rob's bowl, there were 25 + 2 = 27 grapes in Allie's bowl. If Allyn's bowl contained four more grapes than Allie's bowl, there were 27 + 4 = 31 grapes in Allyn's bowl. The total combined number of grapes in all three bowls is 25 + 27 + 31 = 83 grapes. The answer is 83.

Question: Carla needs to drive her car to do a bunch of errands. She needs to drive 8 miles to the grocery store, 6 miles to pick up her kids from school, 12 miles to drop her kids off at soccer practice, and twice the distance from the school to soccer practice to get everyone home again. If Carla's car gets 25 miles per gallon, and gas costs $2.50, how much will Carla have to spend on gas for her trip?
Answer:
First find the distance between soccer practice and home by multiplying the distance between soccer practice and school by 2: 12 miles * 2 = 24 miles. Then find the total distance Carla drives by adding the length of each trip: 24 miles + 12 miles + 6 miles + 8 miles = 50 miles. Then find how many gallons of gas she needs by dividing the distance of the trip by her car's gas mileage: 50 miles / 25 mpg = 2 gallons. Then multiple the gallons of gas by the price per gallon to find the total cost: 2 gallons * $2.50 = $5. The answer is 5.
