Q: Brittany uses 1/4 ounce of shampoo to wash her hair every other day. She buys shampoo in 14-ounce bottles. How many bottles does she need to get her through a leap year?
A: A leap year is one day shorter than a regular year, so it is 365 – 1 = 364 days. Brittany washes her hair every other day, so she will wash it 364 / 2 = 182 times in a leap year. A bottle of shampoo lasts her 14 / 1 / 4 = 14 * 4 = 56 washes. If she buys 3 bottles, she will only have enough for 56 * 3 = 168 washes. If she buys 4 bottles, she will have enough for 56 * 4 = 224 washes. Since 168 < 182 and 224 > 182, Brittany needs 4 bottles of shampoo to get her through a leap year. The answer is 4.
Question: Mcgregor and Floyd were assigned 89 books to read for the week. If Mcgregor was able to finish 34 while Floyd was able to finish 32, how many books do they still have to read?
Answer: They both finished reading a total of 34 + 32 = 66 books. Therefore, they still have to read a total of 89 – 66 = 23 books. The answer is 23.
[Question]Bill gets a flat-screen TV that measures 48 inches by 100 inches. His brother Bob gets a TV that measures 70 inches by 60 inches. If the TVs weigh 4 oz per square inch of screen space, how much more does the heavier TV weigh in pounds? (There are 16 ounces per pound).
[Answer]First find the screen area of Bill's TV: 48 inches * 100 inches = 4800 square inches. Then find the screen area of Bob's TV: 70 inches * 60 inches = 4200 square inches. Then subtract the size of the smaller TV from the size of the bigger TV to find the size difference: 4800 square inches - 4200 square inches = 600 square inches. Then multiply the size difference by the weight per square inch to find the weight difference: 600 square inches * 4 oz / square inch = 2400 oz. Then divide the weight difference in ounces by the number of ounces per pound to find the weight difference in pounds: 2400 oz / 16 oz / pound = 150 pounds. The answer is 150.
Q: I caught 4 fewer fish than the number in my tank and added them to my fish tank. If the tank has 20 fish right now, how many did I add?
A: Let's say the number of fish that was in the tank before was x. If you caught 4 fewer fish than the number that was there, then you caught x - 4. After adding x - 4 fish into the tank, the tank now had 20 fish, meaning the total number of fish in the tank is x + x - 4 = 20. 2x = 20 + 4. The total number of fish that was initially in the tank is 2x = 24. Initially, there were x = 24 / 2 fish in the tank. x = 12. If you caught 4 fewer fish than the number in my tank initially, you caught 12 - 4 = 8 fish. The answer is 8.
Question: On a tough week, Haji's mother sells goods worth $800, which is half the amount she sells on a good week. What's the total amount of money she makes if she has 5 good weeks and 3 tough weeks?
Answer: If on a tough week she sells half what she sells on a good week, then on a good week she sells 800 * 2 = 1600 dollars. If she had 5 good weeks, the amount is 5 * 1600 = 8000 dollars. During the 3 tough weeks, she sells 3 * 800 = 2400 dollars. The total amount she sold in both weeks is 2400 + 8000 = 10400 dollars. The answer is 10400.
