Refer to the attached Wk 3 Graph for this assignment. The graph shows an increase in demand (shifting of the demand curve from D1 to D2). Choose an application or situation in the economy or a specific economic situation to describe this graph. Take into consideration the impact on quantity and price in your analysis.
Given your analysis, what would cause the situation to go the opposite way? What would cause the situation to go further into the same direction?

Yes, because P = MC = MR for each of the 3 firms. ○ B. No, because Firm A is not producing at a profit-maximizing level of output. ○ C. Yes, because all 3 firms are producing at their minimum average total cost. OD. The answer is uncertain since it's unknown whether the firms are producing at the minimum efficient scale or not. ○ E.
