A firms demand function for a good is given by P = 107-2Q and their total cost function is given by TC = 200+3Q. (using for 6.1 to 6.4)
6.1 Obtain an expression for total revenue (price X quantity) in terms of Q
6.2 For what values of Q does the firm breakeven?
6.3 Illustrate the answer to (ii) using sketches of the total cost function, the total revenue function and the profit function
6.4 From the graph estimate the maximum profit and the level of output for which profit is maximized

The market demand function for a good is given by Q = D(p) = 800 − 50p. For each firm that produces the good the total cost function is TC(Q) = 4Q+ Q^2/2 . Recall that this means that the marginal cost is MC(Q) = 4 + Q. Assume that firms are price takers. (a) What is the efficient scale of production and the minimum of average cost for each firm? Hint: Graph the average cost curve first. (b) What...
