Come up with a question and reasoning that would justify [11] as the answer.
The question is: Erin is sorting through the library books to decide which ones to replace. She finds 8 less than 6 times as many obsolete books as damaged books. If she removes 69 books total, how many books were damaged?
Reasoning: Let o be the number of obsolete books and d be the number of damaged books. We know that o + d = 69 and o = 6d - 8. Substituting the first equation into the second equation, we get 6d - 8 + d = 69. Combining like terms, we get 7d - 8 = 69. Adding 8 to both sides, we get 7d = 77. Dividing both sides by 7, we get d = 11.

Come up with a question and reasoning that would justify [2200] as the answer.
The question is: When Doctor Lindsay works in her office, she usually sees 4 adult patients and 3 child patients every hour. If the cost for an adult's office visit is $50, and the cost for a child's office visit is $25, how much money, in dollars, does Doctor Lyndsay receive in a typical 8-hour day for seeing all her patients?
Reasoning: For 4 adult patients per hour, Dr. Lindsay receives 4 * 50 = 200 dollars per hour. For the 3 child patients per hour, Dr. Lindsay receives 3 * 25 = 75 dollars per hour. Thus, Dr. Lindsay receives 200 + 75 = 275 dollars per hour. In an 8 - hour day, Dr. Lindsay receives 8 * 275 = 2200 dollars.

Come up with a question and reasoning that would justify [3] as the answer.
The question is: A certain kind of wild mushroom has either spots or gills, but never both. Gilled mushrooms are rare, with only one growing for every nine spotted mushrooms that grow. A fallen log had 30 mushrooms growing on its side. How many gilled mushrooms were on the fallen log's side?
Reasoning: There is 1 gilled mushroom for every 1 + 9 = 10 mushrooms. Thus, there were 30 / 10 = 3 gilled mushrooms on the fallen log's side.
