Question: Jeremy decides to take Tylenol because of the pain he is experiencing. He decides to take 1000 mg every 6 hours for 2 weeks. How many pills do they take if they are each 500 mg?
Answer: He takes 1000 / 500 = 2 pills each time. He takes them 24 / 6 = 4 times a day. So he takes 4 * 2 = 8 pills per day. He takes pills for 2 * 7 = 14 days. So he takes 8 * 14 = 112 pills. The answer is 112.
[Question]Abigail spent 60% of her money on food, and 25% of the remainder on her phone bill. After spending $20 on entertainment, she is left with $40. How much money did Abigail have initially?
[Answer]Abigail had $20 + $40 = $60 left after paying her phone bill. The $60 is 100% - 25% = 75% of the remainder of her money after spending for food. Since 75% is $60, then 1% is $60 / 75 = $0.80. Thus, Abigail had $0.80 x 100 = $80 left after she spent money on food. The $80 is 100% - 60% = 40% of her original money. So 1% is $80 / 40 = $2. Therefore, Abigail initially had $2 x 100 = $200. The answer is 200.
Q: Whenever Katie and her family eat donuts, they need some coffee to dunk them in. She notices that for each donut they need 2 ounces of coffee. Every pot of coffee she makes contains 12 ounces and costs $3 to make. If her family finishes 3 dozen donuts, how much do they spend on coffee?
A: He family eats 36 donuts because 3 x 12 = 36. They need 72 ounces of coffee for these because 2 x 36 = 72. This is equal to six pots of coffee because 72 / 12 = 6. This will cost $18 to make because 6 x 3 = 18. The answer is 18.
Question: Joe and Adam built a garden wall with three courses of bricks. They realized the wall was too low and added 2 more courses. If each course of the wall had 400 bricks, and they took out half of the bricks in the last course to allow easy checkup of the garden, calculate the total number of bricks the wall has.
Answer: When they added two more courses for the wall, the number of courses became 3 + 2 = 5. Since each course has 400 bricks, the total number of bricks for 5 courses is 5 * 400 = 2000. To allow for an easy checkup of the wall, they removed 1 / 2 * 400 = 200 bricks from the last course of the wall. In total, the wall has 2000 - 200 = 1800 bricks. The answer is 1800.
[Question]The area of square A is 25. The area of square B is 81. What's the length difference between the sides of square A and B?
[Answer]The area of a square is calculated as length * width. Because all a square has all sides equal then we can say that given a side S, the area is S * S. For square A of sides A, the area is A * A = 25 or A^2 = 25. Solving for A we know that A = 5. For square B of sides B, the area is B * B = 81 or B^2 = 81. Solving for B we know that B = 9. The side difference between A and B is 9 - 5 = 4. The answer is 4.
[Question]On a 16 GB (gigabyte) capacity USB drive, 50% is already busy. Calculate the number of gigabytes still available.
[Answer]
We calculate 50% of 16 GB:. 50 / 100 * 16 GB = 0.5 * 16 GB = 8 GB. That leaves 16 GB - 8 GB = 8 GB available on this key. The answer is 8.
