Answer:

17

Step-by-step explanation:

If Nina has 25 books and Arrianne has 8 fewer books than Nina, then the equation would be 25 - 8 ( 25 being Nina's books and 8 being the number of books Arrianne has fewer than Nina ). Since it says "8 books fewer than Nina", we have to subtract the number of books fewer than Nina's in the number of books Nina has. So Arrianne's books is 17 ( because 25 - 8 is 17 ).
