Situation 21-1 Diane's Donuts will begin selling donuts next week. Diane figures that the average variable cost to make each donut will be constant at $0.30. She has already paid $20,000 for the donut-making machinery and one year's rent. Refer to Situation 21-1. What will Diane's total costs be if she sells 2,500 donuts in her first week and then goes out of business? O a. $20,750 b. $30,500 c. $20,880 d. $10,950

3. Costs in the short run versus in the long run Ike's Bikes is a major manufacturer of bicydes. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company's short-run average total cost (SRATC) each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.) Average Total Cost (Dollars per bike) Number of Factories Q = 25 Q = 50 Q = 75 Q = 100 Q = 125 Q = 150 1 440 320 240 320 480 720 2 580 400 240 240 400 580 3 720 480 320 240 320 440 Suppose Ike's Bikes is currently producing 125 bikes per month in its only factory. Its short-run average total cost is S per bike. Suppose Ike's Bikes is expecting to produce 125 bikes per month for several years. In this case, in the long run, it would choose to produce bikes using On the following graph, plot the three SRATC curves for Ike's…

Suppose Honda’s total cost of producing 4 cars is $225,000 and its totalcost of producing 5 cars is $250,000. What is the average total cost of producing 5 cars? What is the marginal cost of the fifth car? • Draw the marginal-cost curve and the average-total-cost curve for a typical firm, and explain why these curves cross where they do.
