Q: Hallie is working as a waitress for $10/hour. On Monday, she works for 7 hours, and she receives $18 in tips. On Tuesday she works for 5 hours, and she receives $12 in tips. On Wednesday she works for 7 hours, and she receives $20 in tips. How much money does she earn in total from Monday to Wednesday?
A: Hallie works a total of 7 + 5 + 7 = 19 hours. For her hourly pay, she earns 19 * $10 = $190. In tips, she receives a total of $18 + $12 + $20 = $50. The total amount of money Hallie earns is $190 + $50 = $240. The answer is 240.
Question: John is 15 cm taller than Lena and 6 cm shorter than Rebeca. If John has a height of 152 cm, what is the height of Lena and Rebeca together?
Answer: Lena is 152 cm - 15 cm = 137 cm tall. Rebeca is 152 cm + 6 cm = 158 cm tall. So, the total height of Lena and Rebeca would be 137 cm + 158 cm = 295 cm. The answer is 295.
[Question]Jill has a difficult test to study for. She decides to study one day for 2 hours. The next day she doubles this amount, and the day after that she studies one hour less than the previous day. How many minutes does Jill study over the 3 days?
[Answer]First, we need to determine how many hours Jill studied in total. To find this out, we begin by performing 2 * 2 = 4 hours spent on day two, double what she spent on day 1. Next, we perform 4 - 1 = 3 hours to determine the amount she studied on the third day. We then add 2 + 4 + 3 = 9 hours spent in total across 3 days. Since there are 60 minutes in an hour, she studied 9 * 60 = 540 minutes in total. The answer is 540.
Q: Mark is filling a punch bowl that can hold 16 gallons of punch. He fills it part way, then his cousin comes along and drinks half the punch in the bowl. Mark starts to refill the bowl and adds 4 more gallons, but then his friend Sally comes in and drinks 2 more gallons of punch. After that, Mark has to add 12 gallons of punch to completely fill the bowl. How much punch did Mark initially add to the bowl?
A: First, figure out how much punch was left in the bowl before Mark refilled it by subtracting the 12 gallons he added from the bowl's total capacity: 16 - 12 = 4 gallons. Next, figure out how much punch was in the bowl before Sally came along: 4 + 2 = 6 gallons. Next, figure out how much punch was in the bowl before Mark started to refill it: 6 - 4 = 2 gallons. Finally, multiply that amount by 2 to find out how much punch there was before the cousin drank half: 2 * 2 = 4 gallons. The answer is 4.
Question: At a bus station, a bus leaves every half-hour for 12 hours a day. How many buses leave the station for 5 days?
Answer: If one bus leaves every half - hour, then during one hour, there are 1 + 1 = 2 buses that leave the station. During 5 days 2 * 12 * 5 = 120 buses leave the station. The answer is 120.
Q: Jerry wakes up one morning and finds the thermostat set to 40 degrees. He set it to double the initial temperature. His dad notices, yells at Jerry, and reducing the temperature by 30 degrees. Later, Jerry's mother reduces the temperature by 30%, before his sister increases it by 24 degrees. What's the final temperature?
A:
First double the initial temperature: 40 degrees * 2 = 80 degrees. Then reduce that amount by 30 to reflect the dad's change: 80 degrees - 30 degrees = 50 degrees. Then multiply that number by 30% to find how much Jerry's mother reduces the temperature: 50 degrees * .3 = 15 degrees. Now subtract 15 degrees from 50 degrees to find the temperature after the mother's change: 50 degrees - 15 degrees = 35 degrees. Finally, add 24 degrees to find the final temperature: 35 degrees + 24 degrees = 59 degrees. The answer is 59.
