(4 marks) Now assume that each firm in the industry has the same market share, so the quantity of tomato cans that each firm produces () is equal to the total sales in the market () divided by the number of participating firms (). Total sales in the market () are equal to $30,000. Derive the firms' average cost to show that the average cost curve (CC) is given by: Curve: b.

Curve: Illustrate the curve and the curve on a graph with price and cost on the vertical axis, and the number of firms on the horizontal axis. Solve for the market equilibrium at Home in autarky, that is, find the equilibrium number of producers and the equilibrium price of canned tomato
