Answer:
The correct answer is option a.
Step-by-step explanation:
The average variable cost is given at $1.50.
The marginal cost is $2.
The quantity of output produced is 50 units.
The average variable cost curve is a U shaped curve. The marginal cost is equal to the average variable cost at its minimum point. So if the marginal cost is higher than the average variable cost it indicates the AVC is increasing.
So the average variable cost for producing 51 units of tacos will be higher than $1.50.
