Explanation / Answer

For your Part 3, The answer is that the firm will stay in the industry stay in the industry as the price is above the AVC (Shut down point in short run) as well as ATC(Shut down point in long run).

Quantity of T-shirts AVC TC=TFC+TVC MC Price TR=PxQ Profit=TR-TC MR ATC 0 - 50,000 - 6 0 -50,000 6 1,000 5.0 55,000 5 6 6,000 -49,000 6 55.0 2,000 4.0 58,000 3 6 12,000 -46,000 6 29.0 3,000 3.0 59,000 1 6 18,000 -41,000 6 19.7 4,000 3.5 64,000 5 6 24,000 -40,000 6 16.0 5,000 4.0 70,000 6 6 30,000 -40,000 6 14.0 6,000 5.5 83,000 13 6 36,000 -47,000 6 13.8 7,000 7.0 99,000 16 6 42,000 -57,000 6 14.1 8,000 9.0 122,000 23 6 48,000 -74,000 6 15.3 9,000 11.0 149,000 27 6 54,000 -95,000 6 16.6 10,000 15.0 200,000 51 6 60,000 -140,000 6 20.0 The break even occurs at the point where Price P or AR equals ATC. The firm is running into losses and at all points the price or average revenue is over the average total costs curve. The firm does not break even. Shut down point is min AVC, which is 3. SO the firm will not shut down in the short run(P=6 and min AVC = 3). But will shut down in the long run as the price is less than min ATC((P=6 and min ATC = 13.8).
