Answer:
Common fixed expense= $15,450
Step-by-step explanation:
First, we need to calculate the total contribution margin from the two divisions:
Domestic Division= $47,800
Foreign Division= 235,000*0.25= $58,750
Total contribution margin= $106,550
Now, we can determine the common fixed expense using the following formula:
Net operating income= total contribution margin - traceable fixed expense - common fixed expense
35,700 = 106,550 - 55,400 - common fixed expense
common fixed expense= 51,150 - 35,700
common fixed expense= $15,450
