Bois Corporation has provided its contribution format income statement for January. The degree of operating leverage is closest to:

A) 0.11
B) 9.37
C) 0.27
D) 3.66

The formula for operating leverage is Contribution Margin / Net Operating Income. We can calculate contribution margin by subtracting total variable expenses from total sales:
Contribution Margin = $380,000 - ($228,000 + $48,000) = $104,000
Net Operating Income = $104,000 - $60,000 = $44,000

Using the above formula, we can calculate the degree of operating leverage for Bois Corporation as:
DOL = ($104,000 / $44,000) = 2.364

However, the question is asking for the degree of operating leverage closest to one of the given options. The closest option to 2.364 is D) 3.66.
