3. Consider a Small and Micro enterprise working in Addis Ababa that has just built a shade that cost 10,000 Birr (fixed cost). Each worker costs 10 burr per hour. Based on this information, fill in the table below. (5 marks) Number of Marginal Variable Total Marginal Worker Hours Output Product Cost Cost Cost Average Total Cost 0 0 50 500 100 1000 150 1300 200 1500 250 1600 300 1650 350 1660 4. The price of a product in a perfect competitive firm is 16 birr and the total cost functions are given as TC= 402-80+15, respectively. Find A. The optimum quantity and the optimum price level (2pts) B. The profit/loss on these levels (2pts) C. At what price should the perfect competitive firm shut down? (1pt) 5. Given market demand:Q = 100 - P, and market supply:P = =- + 10 A. Calculate and interpret the market equilibrium price and quantity. (2.5 pts) B. Determine, whether there is surplus or shortage at P= 25 and P= 40. (2.5pts)
