$40 MC $30 ATC AVC Price $20 P $10 A 0 2 4 5 6 7 Quantity 9

What will this firm decide to do in the long run?

	It will stay in the market because the price is above its AVC at its profit-maximizing output.
	It will leave the market because the price is below its ATC at its profit-maximizing output.
	It will increase its price to point B to earn normal profit.
	It will increase its output until its profit-maximizing output level is equal to B.
	Insufficient data to determine.
