Answer:
$15,450
Explanation:
The computation of the common fixed expenses is shown below:
We know that,
Net operating income = Contribution margin + Sales × contribution margin - traceable fixed expenses - common fixed expenses
$35,700 = $47,800 + $235,000 × 25% - $55,400 - common fixed expenses
$35,700 = $47,800 + $58,750 - $55,400 - common fixed expenses
$35,700= $47,800 + 3,350 - common fixed expenses
So, the common fixed expense would be $15,450
