Answer:
$40
Step-by-step explanation:
Total costs are comprised of total variable costs plus total variable costs. i.e., total costs = variable cost +fixed costs
in this situation,
$10,000 = $6,000 + fixed costs
Fixed costs = $10,000 -$6000
fixed costs = $4000
Average fixed cost is the fixed cost divided by total output
=$4000/100
= $40
