Table. Price Elasticity of Demand and Revenue

Fine 0 10 20 30 40 50

Number of Tickets 0 8 7 6 4 2

Total Revenue

a.Plot the demand curve i.e., Qd = F (p)

b.Use the data in Table IV to find the total revenue for each fine.

SHOW the formula for total revenue.

c.Draw a graph of the relationship between Fines and Revenues [R = f(F)].

d.What does the graph show about the inelastic and elastic portions of the demand curve for tickets.

e.How is the graph in part (c) above as an example of a Laffer Curve.
