4 The Competitive Equilibrium Model—Deriving Supply] Negar owns a trendy and sustainable shoe factory. The total cost of producing a given number of pairs of shoes is displayed in the table below. Assume Negar can only produce the integer quantities of pairs of shoes specified in the table. Number of pairs Total Cost 0 400 10 410 20 430 30 460 40 500 50 580 60 680 70 800 b. Draw the supply curve for Negar’s shoe factory. c. Suppose the wholesale market for shoes that sell to retail stores is competitive, with a market price of $10 per pair (i.e., $100 per 10 pairs). If Negar’s goal is to maximize profits, how many pairs will she choose to sell? d. What are Negar’s profits when she sells the number of pairs from (c) at the market price of $10? e. Calculate Negar’s producer surplus given the price and quantity from part (c). How does this compare to the profit calculated in part (d)?
