Answer:
The true answer:
average fixed cost is 50 cents
Explanation:
The firm produces 400 units of output at a total cost of $1,200.
Average total cost = $1,200/400 = $3.00
Total variable costs are $1,000, total fixed cost = Total cost - total variable costs = $1,200 - $1,000 = $200
Average variable cost = $1,000/400 = $2.50
Average fixed cost = $200/400 = $0.50 (50 cents)
