III. Assume that the the market in the problems above is instead imperfectly competitive - let's say monopolistic competition. Please demonstrate your understanding of this market structure by listing an example price and quantity that a firm within the industry would set. Explain your answer. (Hint: Perfect competition and monopoly are boundaries for which imperfect competition exists between.)
