Answer:
72000/s
Explanation:
In order to find the number of seats in each section, think of 72000 people as the total number of people that need a seat.
If you want to find how many people can go to each section evenly, you need to divide the number of people by the number of sections.
Now that the same number of people are going to each section, this will give you the number of seats in each.
hope this helps!
