Step-by-step reasoning process: 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.
The question and answer:
Question and answer: 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?
The answer is 11

Step-by-step reasoning process: The mural is 6 * 3 = 18 sq meters. So the paint cost 18 * 4 = $72. The artist works for 18 / 1.5 = 12 hours. He charges 12 * 10 = $120. So the total cost is 120 + 72 = $192.
