Consider the weekly market for gyros in a popular neighborhood close to campus. Suppose this market is operating in long-run competitive equilibrium with many gyro vendors in the neighborhood, each offering basically the same gyros. Due to the structure of the market, the vendors act as price takers and each individual vendor has no market power. The following graph displays the supply (S = MC) and demand (D) curves in the weekly market for gyros. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition.

then, plot the supply curve and equilibrium on the second photo

In competitive markets, there are many small firms with each firm unable to influence the market price. Suppose company ABX  operates in the wheat market. The company produces and markets wheats at a Price = $20 per container. The firm’s total costs are given as: TC = 50 +2Q + 3Q2 What level of output should the firm produce? Hint: Set P = MC and solve for Q. Use a graph to show your answers as well

Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run perfectly competitive equilibrium, with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power. The following graph shows the demand (D) and supply curves (S = MC) in the market for hot dogs. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from perfect competition. Use the green point (triangle symbol) to shade the area that represents consumers' surplus, and use the purple point (diamond symbol) to shade the area that represents producers' surplus. PRICE (Dollars per hot dog) 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 0 20 40 Perfectly Competitive Market S=MC D 60 80 100 120 140 160 180 200 QUANTITY (Hot dogs) PC Outcome A Consumers' Surplus Producers' Surplus Assume that one of the hot dog vendors successfully lobbies the city council to…
