Figure 21-4 Quantity of Output Total Fixed Cost Total Variable Cost 0 $25 1 $25 $10 2 $25 $15 3 $25 $25 4 $25 $40 In Figure 21-4, at 3 units of output total cost is Select one: a. $40. b. $50. c. $45. d. $60. e. $65. Figure 21-4 Quantity of Output Total Fixed Cost Total Variable Cost 0 $25 1 $25 $10 2 $25 $15 3 $25 $25 4 $25 $40 In Figure 21-4, at 2 units of output average total cost is Select one: a. $10. b. $15. c. $20. d. $25 e. $30. Solution 1) At 3 units of output, total cost is: option B = $50. Explanation: As we know total cost = total fixed cost + total variable cost, hence here we would have the total cost as: $25 + $25 = $50. 2) At 2 units of output average total cost is: option C = $20. Explanation: As we know, average total cost = Total cost / output. So, here the total cost = total fixed cost + total variable cost = $25 + $15 = $40 Output = 2 Hence average total cost = $40 / 2 = $20. I hope my solution solves your query. Regards. .
