9!: 9x8x7
This is because they are just using 3 seats. Multiply that and you will get your answer. :)
Of course, you want a quick answer right? Well here is the answer, but I hope you know how to do this afterwards. . .

Ohh ty. I got confused
No probs, it's pretty easy once you get the hang of it.
You are "choosing" 3 from 9
The answer of 504 represents the number of permutations, that is, there are distinct places.
e.g. ABC is different from BAC
This is a combination question
number of ways to choose 3 from 9
= C(9,3)
= 84
C(9,3) = 9!/(3!6!)

I understand how you get to 504, but how do you get to 84? Can someone, please help me it would mean a lot!
im a little late, but the equation reiny showed was 9 factorial divided by 3 factorial * 6 factorial.
