[Question]Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate?
[Answer]Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4 * 400 = 1600 feet deep. Twice the depth of the hole that Michael's father dug is 2 * 1600 = 3200 feet. Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200 - 400 = 2800 feet deep. To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800 / 4 = 700 hours. The answer is 700.
Q: For Roger's phone to function optimally, he can have a maximum of 50 apps on his phone. However, the recommended number of apps is 35. If Roger has twice the recommended number of apps, how many apps must he delete for his phone to function optimally again?

Question: Borris liquor store uses 90 kilograms of grapes every 6 months. He is thinking of increasing his production by twenty percent. How many grapes does he need in a year after increasing his production?
Answer: Borris uses 90 x 2 = 180 kilograms of grapes per year. The increase of kilograms of grapes he needed per year is 180 x 0.20 = 36. Therefore, Borris needs 180 + 36 = 216 kilograms of grapes in a year. The answer is 216.
[Question]Kobe and Pau went to a restaurant. Kobe ordered five pieces of fried chicken, and Pau ordered twice as much fried chicken as Kobe did. If they order another set of fried chicken, how many pieces of fried chicken will Pau have eaten in all?

Q: 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?
A: 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.
