Problem

Oslo Company prepared the following contribution format income statement based on a sales volume of 1,000 units (the relevant range of production is 500 units to 1,500 units): Sales $ 40,000 Variable expenses 26,000 Contribution margin 14,000 Fixed expenses 8,680 Net operating income $ 5,320 15. Assume that the amounts of the company's total variable expenses and total fixed expenses were reversed. In other words, assume that the total variable expenses are $8,680 and the total fixed expenses are $26,000. Given this scenario and assuming that total sales remain the same. Using the degree of calculated operating leverage, what is the estimated percent increase in net operating income of a 5% increase in sales?
