Answer:

40320

Explanation:

Imagine placing the figurines on the shelf one at a time.

You have:

  • 8 choices for the first figurine
  • 7 choices for the second figurine
  • 6 choices for the third figurine
  • 5 choices for the fourth figurine
  • 4 choices for the fifth figurine
  • 3 choices for the sixth figurine
  • 2 choices for the seventh figurine
  • and 1 choice for the last (eighth) figurine

So there are 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 8! = 40320 different ways she can arrange the figurines.
