Using the information provided, compute all of the short-run costs for this firm and complete the table (6 points). Please write down the formulae (2 points) and clearly show each cell's full calculation step by step (2 points) to get full marks. Please calculate the values up to 2 decimal points. 2. The following diagram shows three possible SRATC curves and an LRAC curve for a single firm producing light bulbs, where each SRATC curve is associated with a different-sized plant. (10 Points) SRATC SRATC Plant #1 Plant #3 LRAC SRATC Plant #2 Cost per Unit C3 62 0 21 23 Output a. If the firm is producing Q1 light bulbs with Plant #1, what are the firm's average costs? How do you know? b. At Q1, does the firm display decreasing, constant, or increasing costs? Explain. c. How does your answer in part (b) relate to the concept of economies of scale? Explain. d. Repeat parts (a), (b), and (c) for output level Q2 with Plant #2 and output level Q3 with Plant #3
