Lizzy: Sabrina went to the library and found a historical series novel called The Rangers Apprentice. There are 14 books in the series, and each book has 200 pages. She read four books in a month and half the number of books remaining in the second month. What's the total number of pages Sabrina has to read to finish the whole series?.
Me: Hmmm, let me think. I think this is the detailed solution:

The total number of pages in the series is 14 books * 200 pages / book = 2800 pages. Sabrina read 4 books * 200 pages / book = 800 pages in the first month. She still has 14 books - 4 books = 10 books after reading four books. In the second month, she read 1 / 2 * 10 books = 5 books. The total number of pages she read is 5 books * 200 pages / book = 1000 in the second month. In total, Sabrina 1000 pages + 800 pages = 1800 pages in two months. Sabrina has to read 2800 pages - 1800 pages = 1000 more pages to complete the total series. Final answer: 1000.
