[Question]Elvis is releasing a new album with 10 songs, but he doesn't want to waste too much time on writing. He spends 5 hours in the studio, where he writes, records, and edits his songs. Each song takes 12 minutes to record, then it takes 30 minutes to edit all of his songs. How many minutes did it take Elvis to write each song, if each song took the same amount of time to write?
[Answer]5 hours in the studio is the same as 5 * 60 = 300 minutes. To record all of his songs, Elvis takes 12 * 10 = 120 minutes. After editing and recording 300 120 30 = 150 minutes are left to write all of his songs. Songwriting therefore took 150 / 10 = 15 minutes per song. The answer is 15.
Q: Megan is delivering meals on wheels. Out of her 30 clients, 7 need vegan meals, 8 need kosher meals, and three people need meals that are both vegan and kosher. How many meals does Megan deliver that are neither kosher nor vegan?
A: First, add the number of kosher meals to the number of vegan meals: 7 meals + 8 meals = 15 meals. Then subtract the three meals that are both kosher and vegan since they got counted twice: 15 meals - 3 meals = 12 meals. Finally, subtract that number from the total number of meals to find the number of meals that are neither kosher nor vegan: 30 meals - 12 meals = 18 meals. The answer is 18.
Question: For every 1 year a human ages, a dog ages 7 years. When Max is 3, how much older, in dog years, will his 3-year-old dog be?
Answer: The 3 - year - old dog ages 7 years to one human year so he will technically be 3 * 7 = 21 years old in dog years. Max's dog will be 21 when Max turns 3 so the age difference is 21 - 3 = 18. The answer is 18.
[Question]Jackie walks 2 miles each day while Jessie walks 1.5 miles each day. How many more miles, in all, does Jackie walk than Jessie walk in 6 days?

Q: After eating half of the number of fruits he had, Martin remained with twice as many oranges as limes. If he has 50 oranges now, how many fruits did he initially have?
A: Since the number of oranges that Martin has now is twice the number of limes, there are 50 / 2 = 25 limes. The number of fruits she has now is 50 oranges + 25 limes = 75. If she had eaten half of the number of fruits that she had, initially Martin had 2 * 75 = 150 fruits. The answer is 150.
Question: There are 235 books in a library. On Tuesday, 227 books are taken out. On Thursday, 56 books are brought back and 35 books are taken out again on Friday. How many books are there now?
Answer:
