Part (a)

Assuming a single price, illustrate on a diagram and explain how REX would have previously determined the profit maximising price for flights and numbers of flights they offered. (Again, you do not need to show numbers on your diagram).

Part (c)

With the introduction to the market of Qantas, explain the new market structure for flights to this regional centre?

Part (d)
