Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.

It is linear dependency of number of seats sold, S on ticket price, P.
It can be written as:
Where is the constant of proportionality and
is a constant.
Now, putting the given values:
...... (2)
Subtracting (1) from (2):
Putting the value in (1):
Therefore the equation becomes:
