Answer:
a) Syzygy Company is earning zero economic profit, which is good enough to stay in business.
Step-by-step explanation:
market price = marginal revenue = $5 per unit
marginal cost per unit = $5
A perfectly competitive firm will maximize its accounting profits when MR = MC, in this case $5 (MR) = $5 (MC). This also means that the company at this sales and cost level is earning $0 economic profit. In the long run, firms in a a competitive market will always earn $0 economic profit.
