The Zinger Company manufactures and sells a line of sewing machines.Demand per period (Q)for a particular model is given by the following relationship: Q = 400.5P where P is price.Total costs (including a "normal" return to the owners)of producing Q units per period are: TC = 20,000 + 50Q + 3Q2
Zar Island Gas Company is the sole producer of natural gas in the remote island country of Zar.The company's operations are regulated by the State Energy Commission.The demand function for gas in Zar has been estimated as: P = 1,000.2Q where Q is output (measured in units)and P is price (measured in dollars per unit).Zar Island's cost function is: TC = 300,000 + 10Q This total cost function does not include a "normal" return on the firm's invested capital of $4 million.
