The demand is said to be perfectly elastic if the quantity demanded increases infinitely (or by unlimited quantity) with a small fall in price or quantity demanded falls to zero with a small rise in price. The elasticity of demand is given by (dQ / dP)*(P/Q), where P is the price function and Q the demand. Thus, by solving the two equations we have the equilibrium price = $400 per unit of ice cream and the equilibrium quantity= 10,000 units of ice cream. the percentage change in quantity demanded divided by the percentage change in price b. More speciflcally, suppose that the demand curve is given by an equation p = Pd(q).
