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?
