the question is here

A market is characterized by the following demand function: 1 : 500 7P '1 5 Part A [4 marks] At present, only 1 rm operates within this market Assuming it's cost function is TC : 90g + K , where K equals capital costs, determine monopoly output and prot, Part B [2 marks] If there are no barriers to entry and it is plausible that entrants would have similar cost structures relative to the monopolist7 would rms have an incentive to enter this market? Moreover, if rms in comparable markets typically compete on price, what will he the new equilibrium should entry occur? Part C [4 marks] If the monopolist is concerned that another rm with a comparable cost structure is planning on entering this market, what might it do to prevent such entry? Show this result explicitly (ire, calculate the necessary thresholds)
