In a particular market, demand and supply curves are defined by the following equations: P=50 – 0.5QD QS= -20 + 2P where, P is the price in pounds, QS is the quantity supplied and QD is the quantity demanded. (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?
