The demand for a certain commodity is given by D(x) = -50x + 800; that is, x units of the commodity will be demanded by consumers when the price is p = D(x) dollars per unit. Total consumer expenditure E(x) is the amount of money consumers pay to buy x units of the commodity. a) Express consumer expenditure as a function
Consumers' Surplus p = D(q) is the price (dollars per unit) at which q units of a particular commodity will be demanded by the market (that is, all q units will be sold at this price), and q0 is a specified level of production. Find the price p0 = D(q0) at which q0 units will be demanded and compute the corresponding consume
