Answer:
The correct answer is option D.
Explanation:
The total cost of the firm is $600.
The fixed cost is $100.
The variable cost will be
=Total costs-fixed costs
=$(600-100)
=$500.
The average variable cost will be
=total variable costs/quantity of outputs
=$500/100
=$5 per unit
The price is $4.
So, we see the price is not covering the average variable cost. This means the firm is incurring losses. The firm will thus produce zero units of output.
