[Question]A farmer plants his vegetables in neat rows. He has 64 bean seedlings and plants 8 seedlings in a row. He also has 84 pumpkin seeds and plants 7 seeds in a row. Recently, he planted 48 radishes with 6 radishes in a row. If the farmer plants two rows per plant bed, how many plant beds did he have for all his plants?
[Answer]There are 64 / 8 = 8 rows of bean seedlings. There are 84 / 7 = 12 rows of pumpkin seedlings. There are 48 / 6 = 8 rows of radishes. Thus, there are a total of 8 + 12 + 8 = 28 rows of vegetables. Therefore, the farmer had 28 / 2 = 14 plant beds. The answer is 14.

[Question]Cora started reading a 158-page book on Monday, and she decided she wanted to finish it by the end of Friday. She read 23 pages on Monday, 38 pages on Tuesday, and 61 pages on Wednesday. She knows she will have time to read twice as much on Friday as she does on Thursday. How many pages does she have to read on Thursday to finish the book in time?
[Answer]Let P be the number of pages Cora has to read on Thursday. If she finishes the book by the end of Friday, she will have read 23 + 38 + 61 + P + 2P = 158 pages. The pages she has left to read by Thursday are P + 2P = 3P = 158 - 23 - 38 - 61 = pages. Thus, by Thursday she has 3P = 36 pages left to read. Therefore, to finish the book on Friday, Cora has to read P = 36 / 3 = 12 pages on Thursday. The answer is 12.
[Question]Jason bought a new bookcase that can hold a maximum of 80 pounds of weight. Jason has 70 hardcover books that each weigh half a pound, 30 textbooks that each weigh 2 pounds, and 3 knick-knacks that each weight 6 pounds. How many pounds over the bookcase's weight limit is this total collection of items?
[Answer]
First find the total weight of the hardcover books: 70 books * .5 pound / book = 35 pounds. Then find the total weight of the textbooks: 30 books * 2 pounds / book = 60 pounds. Then find the total weight of the knick - knacks: 3 knick - knacks * 6 pounds / knick - knack = 18 pounds. Then find the total weight of all the items: 35 pounds + 60 pounds + 18 pounds = 113 pounds. Then subtract the bookcase's weight limit: 113 pounds - 80 pounds = 33 pounds. The answer is 33.
