What will this firm decide to do in the long run? A-It will stay in the market because the price is above its AVC at its profit-maximizing output. B-It will leave the market because the price is below its ATC at its profit-maximizing output. C-It will increase its price to point B to earn normal profit. D-It will increase its output until its profit-maximizing output level is equal to B. E-Insufficient data to determine. (2) A dairy farmer is operating in a perfectly competitive market.
