A perfectly competitive firm faces the short-run cost schedule shown in Table 1.
A) Calculate average total cost (ATC=TC/Q), marginal cost (MC=∆TC/∆Q) and marginal revenue (MR=∆TR/∆Q) for each level of output. The price per unit of output is £16.
B) Plot ATC, MC and MR on a graph and mark the profit-maximising output. At what output is profit maximised?
C) How much profit/loss is made at the optimum level of output?

- A company in a perfectly competitive market produces an output level Q = 100 where marginal revenue is equal to marginal cost and has the following revenue and cost levels: Marginal cost curve intersects the average variable cost curve at $150. Marginal cost curve intersects the average total cost curve at $200. Marginal cost curve intersects the marginal revenue curve at $170. At Q = 100, ATC = $210 and AVC = $155 At this output of Q = 100, calculate: total revenue (TR), total cost (TC), variable cost (VC), and fixed cost (FC).
