Answer:

There are
8! ways to answer.

Step-by-step explanation:

We know that the survey has 8 items, that means we can use the factorial number, because it's a simple permutation.

Using a factorial we have


n! where
n=8, which is the total number of items.


8! = 8* 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40,320

Therefore, there are 40,320 ways to answer the survey, or 8! ways.
