Question: Daniel has 5 jars of juice containing 2 liters each. He wants to serve a full glass of juice to each person at a party. He knows that each glass can hold up to 250 milliliters of juice. How many full glasses can he give?
Answer: The total liters of juice he has is 5 jars x 2 liters / jar = 10 liters of juice. Then he needs to convert this amount to milliliters: 10 liters x 1000 milliliters / liter = 10,000 milliliters. He can fill up to 10,000 ml / 250 ml / glass = 40 glasses. The answer is 40.

Question: Robby, Jaylen and Miranda are employed at a Cheesecake factory, earning $10 per hour. They work 10 hours a day, five days a week. Robby saves 2/5 of his salary, Jaylene saves 3/5 of his salary, while Miranda saves half of her salary. What are the combined savings of the three employees after four weeks?
Answer: In a day, each of them earns $10 / hour * 10 hours / day = $100 / day. The total number of days each of them work in a month is five days per week * 4 weeks = 20 days. If each of them earns $100 per day, in 20 days, they'll earn 20 days / month * $100 / day = $2000 / month. Robby saves 2 / 5 * $2000 = $800 from his salary. Jaylene's savings is 3 / 5 * $2000 = $1200 of her salary. Miranda saves 1 / 2 * $2000 = $1000 from her salary. The total saving for the three employees is $1000 + $1200 + $800 = $3000. The answer is 3000.

Question: In preparation for the upcoming Olympics, Rita's swimming coach requires her to swim a total of 1,500 hours. Rita has already completed 50 hours of backstroke, 9 hours of breaststroke, and 121 hours of butterfly, but she is unhappy with her inconsistency. She has therefore decided to dedicate 220 hours every month practicing freestyle and sidestroke. How many months does Rita have to fulfill her coach’s requirements?
Answer: So far, time spent practicing backstroke, breaststroke, and butterfly is 50 + 9 + 121 = 180 hours. Since Rita’s must swim 1500 hours, the freestyle and sidestroke practice sessions will take 1500 - 180 = 1320 hours. Rita will practice for 220 hours / month, meaning she will meet her coach’s target in 1320 / 220 = 6 months. The answer is 6.

Question: A washing machine uses 20 gallons of water for a heavy wash, 10 gallons of water for a regular wash, and 2 gallons of water for a light wash per load of laundry. If bleach is used, there is an extra light wash cycle added to rinse the laundry thoroughly. There are two heavy washes, three regular washes, and one light wash to do. Two of the loads need to be bleached. How many gallons of water will be needed?
Answer:
The two heavy washes will use 20 * 2 = 40 gallons of water. The three regular washes will use 10 * 3 = 30 gallons of water. The light wash will use 2 * 1 = 2 gallons of water. The two bleached loads will use an extra 2 * 2 = 4 gallons of water. In all, 40 + 30 + 2 + 4 = 76 gallons of water will be needed. The answer is 76.
