Q: Nurse Missy is attending to the needs of 12 patients in her hospital ward. Most of her patients require standard care, but one-third of her patients have special dietary requirements, which increases the serving time by 20%. At dinner time, she brings each patient their meal. It takes 5 minutes to serve each standard care patient. How long does it take, in minutes, for Missy to serve dinner to all of her patients?
A: Nurse Missy has 12 * (1 / 3) = 4 special needs patients. She has 12 - 4 = 8 standard care patients. Special needs patients take 20% longer to serve, which means serving takes 1.2 * 5 = 6 minutes per patient. To serve dinner to all of her standard care patients, it will take 5 * 8 = 40 minutes. To serve dinner to all of her special needs patients, it will take 6 * 4 = 24 minutes. In total, it will take 40 + 24 = 64 minutes to serve dinner to all of her patients. The answer is 64.
Question: Mrs. Smith wanted to buy wears worth $500. She went to a boutique with the $500 but by the time she had picked out everything she liked, she realized that she would need two-fifths more money than she had. If the shop owner gave her a discount of 15%, how much more money will she still need?
Answer: Two fifths of $500 is (2 / 5) * $500 = $200. She needed $200 more than $500 which is $200 + $500 = $700. 15% of $700 is (15 / 100) * $700 = $105. She was given a $105 discount so she has to pay $700 - $105 = $595. She would still need $595 - $500 = $95. The answer is 95.
[Question]Peter and Kristin are to read 20 fantasy novels each in a week. Peter can read three times as fast as Kristin. If Peter reads one book in 18 hours, how long will Kristin read half of her books?
[Answer]Since Peter reads three times as fast as Kristin, Kristin will take 18 * 3 = 54 hours to read one book. Kristin reads half of her books, a total of 20 / 2 = 10 books. The time Kristin will take to read half of her books is 10 * 54 = 540. The answer is 540.
Q: Tom receives a $12 allowance per month. In the first week, he spends a third of it; in the second week, he spends a quarter of what he has left. How much money does he have left to finish the month?
A: The first week he spends: $12 * 1 / 3 = $4. So he has $12 - $4 = $8 left. In the second week, he spends $8 x 1 / 4 = $2. So Tom has $8 - $2 = $6 left to finish the month. The answer is 6.
Question: Matt did his homework for 150 minutes. He spent 30% of that time on math and 40% on science. He spent the remaining time on other subjects. How much time did Matt spend on homework in other subjects?
Answer: Matt spent on math and science 30% + 40% = 70% of the time. This means he did homework from these two subjects for 70 / 100 * 150 minutes = 105 minutes. So Matt spent 150 minutes - 105 minutes = 45 minutes doing homework from other subjects. The answer is 45.
Q: One student on a field trip counted 12 squirrels. Another counted a third more squirrels than the first student. How many squirrels did both students count combined?
A:
The second student counted 12 / 3 = 4 more squirrels than the first student. The second student counted 12 + 4 = 16 squirrels. Together, the first and second student counted 12 + 16 = 28 squirrels combined. The answer is 28.
