Come up with a question and reasoning that would justify [81] as the answer.
The question is: Mary has a mystery book library. She started with 72 mystery books at the beginning of the year. She joined a book club that sent her 1 book each month of the year. She went to a bookstore halfway through the year and bought 5 more books, then bought 2 books at yard sales later. Her daughter gave her another book for her birthday, and her mother gave her a series of 4 books when Mary visited her. She donated 12 books she didn't want to read again to a charity shop and sold 3 to a used book store. How many books did she have at the end of the year?
Reasoning: Mary got 1 * 12 = 12 books from the book club. She bought 5 + 2 = 7 books. She was given 1 + 4 = 5 books. She got rid of 12 + 3 = 15 books. Thus, at the end of the year she had 72 + 12 + 7 + 5 - 15 = 81 books.

Come up with a question and reasoning that would justify [14] as the answer.
The question is: Julio has four bottles of orange soda and seven bottles of grape soda in his fridge. His friend Mateo has a bottle of orange soda and 3 bottles of grape soda in his fridge. If the amount of beverage in each bottle is 2 liters, how many more liters of soda does Julio have?
Reasoning: Julio has 4 * 2 = 8 liters of orange soda. Julio also has 7 * 2 = 14 liters of grape soda. Julio therefore has a total of 8 + 14 = 22 liters of soda. The amount of orange soda that Mateo has is 1 * 2 = 2 liters of orange soda. In addition, Mateo has 3 * 2 = 6 liters of grape soda. In total, Mateo has 2 + 6 = 8 liters of soda. This means that Julio has 22 - 8 = 14 liters more of soda.

Come up with a question and reasoning that would justify [60] as the answer.
The question is: Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?
Reasoning: Elrond was able to get 20 x 2 = 40 tulips. Therefore, the total number of tulips they were able to get is 40 + 20 = 60.
