Homework Answers

Answer #1

16. Ans: then marginal cost equals average variable cost.

Explanation:

TC = TFC + TVC

MC = change in TC / Change in quantity of output

Since fixed cost is fixed in nature, total cost changes due to change in variable cost only.

AVC = TVC / Q

So, when MC is constant, it means it is equal to AVC.

Thus, option [C] is correct answer

17. Ans: it makes a negative profit that is larger than its fixed costs.

Explanation:

Negative profit means loss. So, if the loss amount is larger than fixed cost means the firm is not able to cover its total amount of fixed cost and a part of variable cost. So, when a firm is not able to cover up all its variable cost, it should shut down.

Thus, option [B] is correct answer
