The figure given below shows the revenue and cost curves of a perfectly competitive firm. Figure 9.5
MC: Marginal cost curve
MR: Marginal revenue curve.
ATC: Average-total-cost curve
AVC: Average-variable-cost curve

A) Total revenue for the firm is area 0BDQ₁.
B) The firm should produce Q₂.
C) Total cost for the firm is area 0P₁EQ₁.
