[Question]Barbara asked the butcher for 4 1/2 pound steaks that cost $15.00/pound. She also asked for a pound and half of chicken breasts that were $8.00 a pound. How much did she spend at the butchers?
[Answer]She ordered 4 1 / 2 pound steaks so that's 4 * .5 = 2 pounds of steak. The steak cost $15.00 a pound and she bought 2 pounds so that's 15 * 2 = $30.00 for 4 steaks. She also needed 1.5 pounds of chicken breasts at $8.00 a pound so that's 1.5 * 8 = $12.00 for chicken. The steaks cost $30.00 and the chicken cost $12.00 for a total of 30 + 12 = $42.00 spent at the butchers. The answer is 42.
Q: Bobby made a big batch of soup weighing 80 kg. Each day the batch gets reduced by half. How many kg will it reach on the fourth day after he made the soup?
A: On the first day, the soup reduces down to 80 / 2 = 40 kg. On the second day, it reduces down to 40 / 2 = 20 kg. On the third day, it is reduced to 20 / 2 = 10 kg. And on the fourth day, it is finally down to 10 / 2 = 5 kg. The answer is 5.
Question: Jeff has a shelter where he currently takes care of 20 cats. On Monday he found 2 kittens in a box and took them to the shelter. On Tuesday he found 1 more cat with a leg injury. On Wednesday 3 people adopted 2 cats each. How many cats does Jeff currently have in his shelter?
Answer: Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = 23 cats. 3 people took a total of 3 * 2 = 6 cats. After Wednesday, Jeff was left with 23 - 6 = 17 cats. The answer is 17.
[Question]Jenny wants to read 3 books in the next 10 days. She can read 100 words per hour. If the first book has 200 words, the second book has 400 words, and the third book has 300 words, how many minutes per day, on average, should she spend reading?
[Answer]She wants to read 200 + 400 + 300 = 900 pages total. She needs to spend 900 / 100 = 9 hours reading in the next three weeks. In minutes, she will need to spend 9 * 60 = 540 minutes. Thus, she should spend 540 minutes / 10 days = 54 minutes per day reading. The answer is 54.
Q: Jonas is a book collector. He has so many books he is converting his third bedroom into a library. This room has 400 square feet of space. He plans to put several bookshelves in the room and each bookshelf takes up 80 square feet of space. If he reserves 160 square feet of space to use for a desk and some walking space, how many shelves can he put in the room?
A: If he reserves 160 sq. ft. of space for a desk and some walking space, then he will have 400 - 160 = 240 sq. ft. of space remaining. If each bookshelf takes up 80 sq. ft. of space, then 240 sq ft can contain 240 / 80 = 3 bookshelves. The answer is 3.
Question: Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?
Answer:
5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00. The answer is 23.
