A firm's primary objective is to maximise its total sales revenue.
This means the firm should choose to produce the level of output where
marginal revenue is equal to zero (MR=0MR = 0MR=0).
marginal revenue is equal to marginal cost (MR=MCMR = MCMR=MC).
average revenue is equal to average total cost (AR=ATCAR = ATCAR=ATC).
average revenue is equal to marginal cost (AR=MCAR = MCAR=MC).
