Douglas Fur is a small manufacturer of fake-fur boots in San Diego. The following table shows the company’s total cost of production at various production quantities.
On the following graph, plot Douglas Fur’s average total cost (ATC) curve using the green points (triangle symbol). Next, plot its average variable cost (AVC) curve using the purple points (diamond symbol). Finally, plot its marginal cost (MC) curve using the orange points (square symbol). (Hint: For ATC and AVC, plot the points on the integer; for example, the ATC of producing one pair of boots is $210, so you should start your ATC curve by placing a green point at (1, 210). For MC, plot the points between the integers: For example, the MC of increasing production from zero to one pair of boots is $90, so you should start your MC curve by placing an orange square at (0.5, 90).)
Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.
Douglas Fur is a small manufacturer of fake-fur boots in Dallas. The following table shows the company’s total cost of production at various production quantities.
On the following graph, plot Douglas Fur’s average total cost (ATC) curve using the green points (triangle symbol). Next, plot its average variable cost (AVC) curve using the purple points (diamond symbol). Finally, plot its marginal cost (MC) curve using the orange points (square symbol). (Hint: For ATC and AVC, plot the points on the integer; for example, the ATC of producing one pair of boots is $155, so you should start your ATC curve by placing a green point at (1, 155). For MC, plot the points between the integers: For example, the MC of increasing production from zero to one pair of boots is $95, so you should start your MC curve by placing an orange square at (0.5, 95).)

One day he gives you the following data at his present level of production: Output = 2000 pounds, market price = $5.00, total cost =$8000, fixed cost=$2000, marginal cost=$5. The minimum of AVC occurs at {1000 pounds at $2} and the minimum of ATC at {1500 pounds at $3.5}. Please help Jack with the following questions based on the above figures: Draw a graph for the raw cotton market and a graph for Jack’s farm current situation that includes MC, ATC, and AVC, labeling all relevant points on axes with numerical values. Is Jack maximizing the profit (minimizing the loss)? Why or why not? Label the total profit/loss area. Suppose more farmers enter the raw cotton market until the market price is $3.00 per pound. On the same graphs, show the effect of this change in the market place. Would you like to suggest Jack leaving the market in the short run? Explain your answer.arrow_forward4.
