Answer:
5 seats
Step-by-step explanation:
if I'm getting the right idea, the seats are NOT enough
since the number of arrangement of 10 people in a row is
10! = 3628800 which is a lot larger than 30240.
---------------------------------------------------------------------------------------
Let number of seats be
10PX = 30240
= 30240
(10-X)! = 
(10-X)! = 120
(10-X)! = 5!
10-X = 5
X = 5
Answer:
The answer is A. If not then I'm sorry ☹
