Answer 2

Answer:

• Ticket increase by 5=15+5=20

so.

• Sold ticket decrease by 20 =1200 - 20 =1180

so we use coordinates to find demand function.

(1200,15) (1180,20)

1. slope= 20-15/1180-1200= -5/20 =-0.25
2. By using equation of straight line

• y - y1 = slope(x - x1)
• y - 15 = -0.25(x - 1200)
• y= -0.25x + 315

Sum up
