[Question]The total number of dogs at an animal rescue center is 200. Mr. Tanner, the manager at the rescue center, gets a call that 100 dogs at another rescue center are to be moved because of weather problems. He agrees to bring the dogs to his rescue center, and after one week, gives out 40 animals for adoption. After a month, 60 more dogs were adopted by dog lovers. What's the total number of remaining animals in the adoption center after the last adoptions?
[Answer]After taking in 100 more dogs, the number of dogs in the rescue center increased to 200 + 100 = 300. After a week, the number of dogs was reduced to 300 - 40 = 260 after the adoptions. So, there are 260 - 60 = 200 dogs left after 60 more dogs were adopted. The answer is 200.
Q: Hadley loves to do volunteer work at the local library. On a certain day, she neatly arranges 100 books on the shelf. By lunchtime, a certain number of books had been borrowed. She added 40 more books to the same shelf. By evening, 30 more books had been borrowed. If the shelf had 60 books remaining by the evening, how many books had been borrowed by lunchtime?
A: Let x be the number of books borrowed by lunchtime. So by lunchtime, the remaining number of books will be 100 - x. After adding 40 more books, the total number of books increased to 100 - x + 40. By evening, after 30 more books have been borrowed, the total number of books remaining is 100 - x + 40 - 30 = 60. Thus 110 - x = 60. Thus x = 50 books. The answer is 50.
Question: In one hour, Addison mountain's temperature will decrease to 3/4 of its temperature. If the current temperature of the mountain is 84 degrees, what will the temperature decrease by?
Answer: In one hour, Addison mountain's temperature will decrease to 3 / 4 of the temperature it is now, meaning the temperature will decrease to 3 / 4 * 84 = 63 degrees. The temperature decrease will be 84 - 63 = 21 degrees. The answer is 21.
