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 [33] as the answer.
The question is: John has 54 pieces of gum, Cole has 45 pieces of gum and Aubrey has no pieces of gum. They decide to share the gum equally between the 3 of them. How many pieces of gum will each one get?
Reasoning: Total pieces of gum are 54 pieces + 45 pieces + 0 pieces = 99 pieces. When the pieces are shared equally amongst 3 people, each one gets 99 pieces / 3 people = 33 pieces / person.

Come up with a question and reasoning that would justify [295] as the answer.
The question is: John throws a block party and splits the cost with 3 other people. They buy 100 pounds of burgers at $3 per pound. They also buy $80 of condiments and propane to cook everything. John also buys all the alcohol which costs $200. How much did John spend altogether
Reasoning: He splits the cost 3 + 1 = 4 ways. 100 pounds of burgers at $3 per pound makes 100 * 3 = $300. In addition to $80 for condiments and propane the total cost was 300 + 80 = $380. That means each of them paid 380 / 4 = $95. Then adding in the cost of alcohol, John spent 200 + 95 = $295.
