Question: Big Lots is having a sale. All chairs are 25% off. If you buy more than 5 chairs, you get an additional 1/3 off the discounted price of the number of chairs over 5. If you bought 8 chairs that were normally priced at $20, how much do the chairs cost in total?
Answer: You save $5 per chair with the 25% off sale. On sale chairs cost $15 each because 20 - 5 = 15. You bought 3 chairs above the 5 required before the extra savings starts because 8 - 5 = 3. You save an extra $5 on these chairs because 15 x (1 / 3) = 5. The first five chairs cost $75 in total because 5 x 15 = 75. The final three chairs cost $30 in total because 3 x 10 = 30. In total they cost $105 because 75 + 30 = 105. The answer is 105.
[Question]Carla needs to dry-clean 80 pieces of laundry by noon. If she starts work at 8 AM, how many pieces of laundry does she need to clean per hour?
[Answer]First find how many hours Carla has to work: 12:00 - 8:00 = 4 hours. Then divide the total amount of laundry by the number of hours to find how many pieces Carla has to clean per hour: 80 pieces / 4 hours = 20 pieces / hour. The answer is 20.
Q: There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm?
A: First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = 3 weeks. Then multiply that number by the number of days per week: 3 weeks * 7 days / week = 21 days. Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish / day = 42 fish. Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = 68 fish. Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = 26 fish. The answer is 26.
Question: A business executive is going on a four day vacation where he will be unable to answer emails. The first day he is gone, he receives 16 new emails. On each of the following days, he receives half as many new emails as he received on the prior day. At the end of his four day vacation, how many new emails will he have received in total?
Answer: On the second day, the executive receives 16 / 2 = 8 new emails. On the third day, he receives 8 / 2 = 4 new emails. On the fourth day, he receives 4 / 2 = 2 new emails. Therefore, during the entire trip he will have received 16 + 8 + 4 + 2 = 30 new emails. The answer is 30.
[Question]A swimming pool is being emptied through a drain at the bottom of the pool and filled by a hose at the top. The drain can empty the pool in 4 hours and the hose can fill the pool in 6 hours. The pool holds 120 liters of water. If the pool starts filled with water, how much water will be left after 3 hours?
[Answer]It takes the drain 4 hours to empty the pool, so it drains at a rate of 120 liters / 4 hours = 30 liters / hour. After 3 hours, the drain will have removed 3 * 30 = 90 liters of water from the pool. It takes the hose 6 hours to fill the pool, so it fills at a rate of 120 liters / 6 hours = 20 liters / hour. After 3 hours, the hose will have added 3 * 20 = 60 liters of water to the pool. After 3 hours, there will be 120 liters + 60 liters – 90 liters = 90 liters of water left in the pool. The answer is 90.
