Find the equilibrium quantity and price using the equations. b) Suppose income rises to 24. Find out the changes in equilibrium price and quantity. 4. Consider a linear demand curve, Q = 120 – 4P. a) What is the price elasticity of demand at P = 20? b) At what price demand is unit elastic (i.e. elasticity = –1)?...
