C=5/9 (62-32)
c=(5/9)*30
c= 150/9
c=16.666....
so c=16.6
Answer:

Step-by-step explanation:
Given
Let x represent the number of tickets, and p the charges

A reduction of 50c gives an increment of 50 tickets.
This gives:
---- 

Required
Determine the demand function
First, calculate the slope:




So, the equation is:




Hence, the function is:

Area of triangle=1/2bh
Area=248ft
Base=x
Height=2x-1
248=1/2×x×(2x-1)........
