Need help with these 3 steps of this problem.

14. 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 $27,720 and the total fixed expenses are $73,500. Under this scenario and assuming that total sales remain the same, what is the degree of operating leverage? (Round your answer to 2 decimal places.) 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): Using the degree of operating leverage, what is the estimated percent increase in net operating income that would result from a increase in unit sales? (Round your intermediate calculations and final answer to 2 decimal places.) 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 $27,720 and the total fixed expenses are $73,500. Using the degree of operating leverage, what is the estimated percent increase in net operating income of a 5% increase in unit sales? (Round your intermediate calculations and final answer to 2 decimal places.)
