[Question]Allison, a YouTuber, uploads 10 one-hour videos of food reviews each day to her channel. She uploaded videos halfway through June, at that pace, and then doubled the number of video hours she uploaded on the remaining days. What's the total number of video hours she has uploaded at the end of the month?
[Answer]Since June has 30 days, halfway is 1 / 2 * 30 = 15. The total number of video hours halfway through June is 10 * 15 = 150. When she doubled the number of video hours, the total per day became 10 * 2 = 20. The total number of video hours for the remaining days is 15 * 20 = 300. The total number of video hours for the whole month is 300 + 150 = 450. The answer is 450.
Q: On Monday Samson ate 3 sandwiches at lunch and ate twice as many at dinner. The next morning, he felt sick from eating all those sandwiches, so he only ate one sandwich for breakfast. How many more sandwiches in total did Samson eat on Monday than Tuesday?
A: Samson ate 3 sandwiches x 2 = 6 sandwiches at dinner on Monday. He ate 3 sandwiches + 6 sandwiches = 9 sandwiches total on Monday. Therefore, he ate 9 sandwiches - 1 sandwich = 8 more sandwiches on Monday than Tuesday. The answer is 8.
Question: 25% of oysters have pearls in them. Jamie can collect 16 oysters during each dive. How many dives does he have to make to collect 56 pearls?
Answer: First find how many pearls Jamie collects per dive by multiplying the number of oysters by the chance each oyster has a pearl: .25 pearls / oyster * 16 oysters / dive = 4 pearls / dive. Then divide the number of pearls he wants by the number of pearls per dive to find the number of dives: 56 pearls / 4 pearls / dive = 14 pearls / dive. The answer is 14.
[Question]Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
[Answer]Her first drink consumed 1 / 4 * 4 = 1 liter of water. Thus there were 4 - 1 = 3 liters of water left in the bottle. Next, she drank 2 / 3 * 3 = 2 liters. Thus, there were 3 - 2 = 1 liters remaining. The answer is 1.
Q: John needs to replace his shoes so he decides to buy a $150 pair of Nikes and a $120 pair of work boots. Tax is 10%. How much did he pay for everything?
A: The shoes cost $150 + $120 = $270. The tax was $270 * .1 = $27. So the total cost was $270 + $27 = $297. The answer is 297.
Question: Jill can run up a hill at 9 feet/second and down a hill at 12 feet/second. How long does it take her to run up and down a 900 foot hill?
Answer:
First find the time it takes Jill to run up the hill: 900 feet / 9 feet / second = 100 seconds. Then find the time it takes Jill to run down the hill: 900 feet / 12 feet / second = 75 seconds. Then add the two times to find Jill's total time: 100 seconds + 75 seconds = 175 seconds. The answer is 175.
