Answer:
$10
Explanation:
Data provided in the question
Number of units produced = 20 units
Average fixed cost = $25
Average total cost = $35
Marginal cost = $15
As we know that
Average total cost = Average fixed cost + average variable cost
$35 = $25 + average variable cost
So, the average variable cost is
= $35 - $25
= $10
The average total cost is the sum of average fixed cost and the average variable cost
