Hi, I need help with this microeconomics question please, thank you !

Question 1 [20 points] The graph below shows the demand faced by Echo Systems, a monopolist, which incurs only fixed costs and therefore has a marginal cost equal to zero. Note: If necessary round your answers to two decimal places. a) Suppose that a new firm, which also has zero marginal costs, enters this industry and assumes that Echo Systems will continue to produce its current output. Plot the existing firm's marginal revenue line, new firm's marginal revenue line, and new firm's demand line. Marginal Revenue Demand N Cost ($) 12 18 24 30 36 42 48 54 60 66 72 78 Reset Units of Output b) Before the new firm disrupted Echo Systems' monopoly what was the price Echo Systems charged, and what quantity of output did it produce? Price = $ 0 Output = 0 c) What output will the new firm choose to produce, and what will be the new market price, given both firms' output? New Market Price = $ 0 New Firm's Output = 0
