Prove that price elasticity of demand is not the same as the slope of a demand curve.
(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?

(a) What is the equilibrium price and quantity? (b) What is the price elasticity at a price of £35? (c) What do you expect will happen to total expenditure on this good if the price increases from £35 to £40? Is this expectation confirmed if you calculate the total revenue for each price?
