The ways 1st - 3rd place are ordered matter, so we aren't finding the combination. We;re finding the permutation. This means we have 8 contestants taken 3 ways. The number of permutations of n objects taken r at a time is nPr = n! / (n - r)! N is 8 and 3 is R. Substitute the values.

8P3 = 8! / (8 - 3)! → 8! / 5! → 336

(You can also input this in a scientific calculator by pressing "8", then "nPr" then "3")

-4 = x -1
+1 +1
-3=x

This means x is equal to -3. Hope this helps!
