Question: Patricia has 4 barrels of 7 gallons each. All of them are empty, and there's only one faucet with a flow rate of 3.5 gallons per minute. How many minutes will it take to fill all 4 barrels?
Answer: If Patricia has 4 barrels and each barrel has 7 gallons, then in total she needs 4 * 7 = 28 gallons. If the faucet can provide 3.5 gallons every minute, then she will need 28 / 3.5 = 8 minutes to fill all 4 barrels. The answer is 8.

Question: Norma takes her clothes to the laundry. She leaves 9 T-shirts and twice as many sweaters as T-shirts in the washer. When she returns she finds 3 sweaters and triple the number of T-shirts. How many items are missing?
Answer: Norma left 9 T - shirts And twice as many sweaters, she took 9 * 2 = 18 sweaters. Adding the T - shirts and sweaters, Norma left 9 + 18 = 27 clothes. When she came back, she found 3 sweaters And triple the number of T - shirts, she found 3 * 3 = 9 T - shirts. Adding the T - shirts and sweaters, Norma found 3 + 9 = 12 clothes. Subtracting the clothes she left from the clothes she found, 27 - 12 = 15 clothes are missing. The answer is 15.

Question: James hires a seamstress to fix all his shirts and pants. He has 10 shirts and 12 pairs of pants. It takes 1.5 hours to fix a shirt and twice as long for pants. The tailor charges $30 per hour. How much does it cost?
Answer:
It takes 10 * 1.5 = 15 hours to fix his shirts. It takes 1.5 * 2 = 3 hours per pair of pants. So it takes 3 * 12 = 36 hours for the pants. That means in total it takes 15 + 36 = 51 hours. So it cost 51 * 30 = $1530 to fix everything. The answer is 1530.
