Question 6.  (20 points)  The licorice industry is competitive. The current market price of a string of licorice is $0.50.  At this price, a firm decides to produce 2 million strings of licorice this month.  The total fixed cost per month is $400,000 and the average variable cost of $0.40

1. a. What is the marginal cost of a string at 2 million strings of production level?

1. b.Assuming that one month is considered a short run, is the firm’s decision to produce 2 million strings of licorice this month right or wrong?  Explain the reason.
