[Question]James replaces the coffee for the household. There are 3 other people in the house and everyone drinks 2 cups of coffee a day. It takes .5 ounces of coffee per cup of coffee. If coffee costs $1.25 an ounce, how much does he spend on coffee a week?
[Answer]There are 3 + 1 = 4 people in the house. So they drink 4 * 2 = 8 cups of coffee a day. That means they use 8 * .5 = 4 ounces of coffee a day. So they use 4 * 7 = 28 ounces of coffee a week. So he spends 28 * 1.25 = $35. The answer is 35.
Q: An airplane took a trip along the Eastern Coast of the USA. During the trip, the plane hovered in Mountain time for 3 hours, Central time for 4 hrs, and Eastern time for 2 hrs. The next day it took 2 more hours to hover in each of the places it passed through the previous day. Calculate the total time it took the plane to hover over Mountain time, Central time, and Eastern time in the two days.
A: The total time it took to hover over the Mountain and the central time is 3 + 4 = 7 hours. If it hovered further to the Eastern time zone, it took a total of 7 + 2 = 9 hours to cover the whole trip. The next day, it took 2 more hours to cover each of the places it passed through the previous day, taking a total of 2 * 3 = 6 hours. The total time it took on the second day to cover the distance it covered the previous day is 9 + 6 = 15 hours. In total, the train took 15 + 9 = 24 hours to hover over the places in the two days. The answer is 24.

Q: Zach was a waiter in a fancy restaurant. His last table for the night was a party for 4 people. The mom ordered lobster for $25.50, the dad ordered steak for $35.00 their twin boys both ordered a cheeseburger and fries for $13.50 each. They started their meal with an appetizer that cost 8.50. Everyone also ordered a dessert that cost $6.00 each. They wanted to give a 20% tip for Zach on the bill. What did the final bill total come to?
A: The twins ordered a cheeseburger each so 2 * 13.50 = $27.00 for both cheeseburgers. Everyone ordered a dessert so 4 * 6 = $24.00 for dessert. When you add all the meals together they spent 25.50 + 35.00 + 27.00 + 8.50 + 24.00 = $120.00. Zach's tip was 20% so .20 * 120.00 = $24.00. When you add up the meals $120.00 and Zach's tip of $24.00 then the total cost is 120.00 + 24.00 = $144.00. The answer is 144.
Question: Jack goes up three flights of stairs, then down six flights of stairs. If each flight of stairs has 12 steps that each each 8 inches high, how many feet further down is Jack than when he started?
Answer:
First find the number of inches in each flight of stairs: 12 steps * 8 inches / step = 96 inches. Then find the net number of flights of stairs Jack went down: 6 flights - 3 flights = 3 flights. Then multiply than number by the number of inches per flight to find how many inches further down he is: 96 inches / flight * 3 flights = 288 inches. Then divide that number by 12 to find the number of feet down he is: 288 inches / 12 inches / foot = 24 feet. The answer is 24.
