Answer:
$20
Step-by-step explanation:
First, we need to find the total cost of producing 100 cookies.
From the above question, the total cost to produce 100 cookies is given by the average total cost of $0.25 multiplied by 100 units
TC = $0.25 × 100 = $25.
Therefore, the total cost to produce 50 cookies, is equal to the cost of producing 100 units minus the marginal cost ($0.10 per unit) of the additional 50 units.
TC = $25 - ($0.1 × 50) = $20
