Find the consumers' surplus and the producers' surplus at the equilibrium price level for the given price-demand and price-supply equations. Include a graph that identifies the consumers' surplus and the producers' surplus. Round all values to the nearest integer. p = D(x) = 140e- 0.004x. p = S(x) = 20 0.004x The value of x at equilibrium is (Round to the nearest whole number as needed.)
