Answer:
[tex]y=-2500x+56500[/tex]
Step-by-step explanation:
We need to write expression of the attendance in terms of the price of the tickets. We can determine the percentage increase of the attendance by decreasing the tickets price. We can have two points:
(11,29000) and (9,34000)
We have calculate the slope:
[tex]m=(34000-29000)/(9-11)=-2500[/tex]
Substitute point into:
[tex]y=mx+c[/tex]
[tex]29000=-2500(11)+c[/tex]
[tex]c=56500[/tex]
The equation is:
[tex]y=-2500x+56500[/tex]
where x is the ticket price and y is the attendance.
