Gayne corporation's contribution margin ratio is 12% and its fixed monthly expenses are $84,000. if the company's sales for a month are $738,000, what is the best estimate of the company's net operating income? assume that the fixed monthly expenses do not change.

the net operating income is 4.560

Explanation:

Net operating income is a calculation of revenues less cost, minus all reasonably necessary operating expenses. Having said that we can determine that the fixed expenses are included in the necessary operanting expenses unless they include depreciations and amortization. Since the text doesn’t refer to the fixed expenses as depreciations or amortization the calculation is this:

Calculate the cost if the contribution margin is 12%

Cost is equal to = (Revenue*(1-contribution ratio))= (738.000*(1-0.12))= 649.440

Then calculate the net operating income  

Net operating income = (Revenue – Cost-operating expenses) = (738.000-649.440-84.000) = 4.560
