When marginal cost exceeds average total cost, which of the following must be true?   Question 14 options:   Marginal cost must be falling.   Average total cost must be falling.   Average total cost must be rising.   Average fixed cost must be rising.

Costs (Q) = 4Q^2 + 144 What is average total cost? What is marginal cost?

Marginal cost, average total cost and average variable cost Marginal cost and average total cost are always equal. Do you agree? Explain. If you disagree then write under what situation they are equal. b. Marginal cost and average variable cost are always equal. Do you agree? Explain. If you disagree then write under what situation they are equal.

Nokia sells a new budget cell phone. Based on information provided by the accounting department, the average variable cost is: AVC = $30 + Q %3D The average fixed cost is: AFC = $9,000,000/Q where Q is the number of phones. The phone sells for $50. Show your work/thought process: a. Find the total cost, average cost, and marginal cost equations. b. At what level of output is average total cost minimized?

With appropriate examples explain how marginal cost is related only to total variable cost.
