Q: Adam has just bought some new books so he has decided to clean up his bookcase. After he adds his new books to his bookshelf he realizes that he has bought enough books to finish completely filling his bookcase with 2 books left over. Before his shopping trip, Adam had 56 books in his bookcase. If his bookcase has 4 shelves and averages 20 books per shelf, how many books did Adam buy on his shopping trip?
A: Adam’s bookshelf has 4 shelves that fit 20 books each, which is 4 * 20 = 80 books in total to fill the bookshelf. Adam ended the day with a full bookcase of 80 books in the bookcase and 2 books left over, 80 + 2 = 82 books total. If Adam started the day with 56 books and ended the day with 82 books then Adam bought 82 - 56 = 26 books bought on his shopping trip. The answer is 26.
Question: Caitlin makes bracelets to sell at the farmer’s market every weekend. Each bracelet takes twice as many small beads as it does large beads. If each bracelet uses 12 large beads, and Caitlin has 528 beads with equal amounts of large and small beads, how many bracelets can she make for this weekend?
Answer: Caitlin has 528 / 2 = 264 small beads. Each bracelet needs 12 * 2 = 24 small beads. Thus, Caitlin can make 264 / 24 = 11 bracelets for the farmer’s market this weekend. The answer is 11.
[Question]In five years, Rehana will be three times as old as Phoebe. If Rehana is currently 25 years old, and Jacob, Rehana's brother, is 3/5 of Phoebe's current age, how old is Jacob now?
[Answer]If Rehana is currently 25 years old, she will be 25 + 5 = 30 in five years. Rehana will be three times as old as Phoebe in five years, meaning Phoebe will be 30 / 3 = 10 years old in five years. Currently, Phoebe is 10 - 5 = 5 years old. 3 / 5 of Phoebe's age now is 3 / 5 * 5 = 3 years, which is Jacob's age. The answer is 3.

Question: Tracy has a charity book collection store from which she receives book donations from members of her town. Any person who wants to borrow a book is free to do so as long as they return the book after they've finished reading. She has already received 300 book donations. If ten people come and donate five books each in a week, and a total of 140 books are borrowed by other people to read, calculate the total number of books she has remaining in the store?
Answer: The ten people donated 10 * 5 = 50 books. The total number of books in her store after the new donations is 300 + 50 = 350 books. When some of the books are borrowed, her total collection becomes 350 - 140 = 210 books. The answer is 210.
