Q: Colston knows that his teacher loves drinking coffee and one day wants to see how much she drinks each week. He sees that she has a 20-ounce thermos and when she makes her coffee she pours a 1/2 cup of milk in, and then fills the coffee to the top. She does this twice a day. After the five-day school week, he decides to tell her, and when she hears how much coffee she drinks, she decides to drink 1/4 of what she normally drinks. How many ounces of coffee does she now drink a week?
A: 1 / 2 a cup = 4 ounces. Each thermos contains 16 ounces of coffee because 20 - 4 = 16. She drinks 32 ounces a day because 2 x 16 = 32. She drinks 160 ounces a week because 32 x 5 = 160. She starts drinking only 40 ounces because 160 / 4 = 40. The answer is 40.
Question: John joins a country club with 3 other members of his family. The fee to join is $4000 per person. There is also a monthly cost of $1000 per person. John pays half the cost. How much does John pay for the first year?
Answer: There are 3 + 1 = 4 members joining. So the cost is 4 * 4000 = $16,000 to join. The monthly fee comes out to 1000 * 12 = $12,000 per person per year. So that is 12000 * 4 = $48,000. So the total cost is 16,000 + 48,000 = $64,000. So John pays 64000 / 2 = $32,000. The answer is 32000.
[Question]Carla needs to dry-clean 80 pieces of laundry by noon. If she starts work at 8 AM, how many pieces of laundry does she need to clean per hour?
[Answer]First find how many hours Carla has to work: 12:00 - 8:00 = 4 hours. Then divide the total amount of laundry by the number of hours to find how many pieces Carla has to clean per hour: 80 pieces / 4 hours = 20 pieces / hour. The answer is 20.
Q: Jon makes 3/4's the salary that Karen makes. John makes $3000 per month. How long will it take him to make the same amount of money that Karen does in 3 months?
A: Karen makes $3000 / (3 / 4) = $4000 per month. In three months, Karen would make a total of $4000 * 3 = $12000. To make the same amount of money John would need to work $12000 / $3000 = 4 months. The answer is 4.
Question: A captain steers his ship 100 miles north on the first day of their journey. On the second day, he sails to the east three times as far as the distance as he covered on the first day. On the third day, the ship travels further east for 110 more miles than the distance it covered on the second day. What is the total distance the ship has traveled in the three days?
Answer: If the ship traveled 100 miles to the north, it sailed for a distance of 3 * 100 miles = 300 miles to the east on the second day. On the third day, the sheep sailed for 300 miles + 110 miles = 410 miles. The distance covered by the ship in the three days is 410 miles + 300 miles + 100 miles = 810 miles. The answer is 810.
