Division B had a contribution margin ratio of 40% and its sales were $232,000. Net operating income for the company was $32,600 and traceable fixed expenses were $55,800. Corbel Corporation's common fixed expenses were:. a) $48,700
b) $55,800
c) $104,500
d) $137,100

a. $48,700

Explanation:

Contribution margin  for Division A = $44,300

Contribution margin  for Division B = 40% * Sales Value = 40% * $232,000 = $92,800

Total contribution margin = $44,300 + $92,800 = $137,100

Office Segment Margin =Total contribution margin - Traceable fixed expenses

Office Segment Margin = $137,100 - $55,800

Office Segment Margin = $81,300

Net Operating Income = Office Segment Margin - Common Fixed Expenses

Common Fixed Expenses = Office Segment Margin - Net Operating Income

Common Fixed Expenses = $81,300 - $32,600

Common Fixed Expenses = $48,700

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
