Answer:
80
Explanation:
Total cost = fixed cost + variable cost
Average total cost = average fixed cost + average variable cost.
Average total cost = Total cost / quantity
Average fixed cost = fixed cost / quantity
Average variable cost = variable cost/ quantity
$15 = average fixed cost + $12
Average fixed cost = $3
Total fixed cost = $240
$3 = $240 / q
Q = 80
