Which scenario about books represents finding the difference?

One scenario that represents finding the difference with books could be:

Samantha has a collection of 20 books, and she decides to donate 8 of them to the library. To find the difference, she subtracts the number of books she donated (8) from her original collection (20). The difference is 12, meaning Samantha would have 12 books remaining after donating 8.

One scenario about books that represents finding the difference is comparing the number of pages in two different books. To find the difference, you would subtract the number of pages in one book from the number of pages in the other book. For example, if Book A has 300 pages and Book B has 250 pages, the difference in the number of pages would be 300 - 250 = 50.
