A monopolist has its total costs (TC) of production given in Table 3. The (inverse) demand

curve it faces in the market is described by this equation: P = a − bQ = 3, 000 − (31.15)Q. Table 3: Total Costs for a Monopolist

3(b). Draw the MC and ATC curves using the values derived for 3(a). Draw the inverse demand curve and its corresponding MR curve. Note: for the MR curve, be sure to use the equation learned in class, M R = a − 2bQ.

3(c). What is the price (PM ) and quantity (QM ) that the monopolist will choose in order to maximize pro t?

3(d). What is their total pro t from the price and quantity combination in 3(c)?3(e). What is the consumer surplus when they charge the price PM from 3(c)?

3(a):

I've calculated MC and ATC in the table below. I've also calculated price based on the inverse demand formula: 3000 - 31.15Q and the Marginal revenue based on the formula: 3000 - 62.3Q.
