A. What is the margin of safety in dollars? What is the margin of safety percentage?

B. What is the degree of operating leverage? (Round your answer to 2 decimal places.)

C. Using the degree of operating leverage, what is the estimated percent increase in net operating income of a 5% increase in sales? (Round your intermediate calculations and final answer to 2 decimal places.)

D. Assume that the amounts of the companys 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.)

E. Assume that the amounts of the companys 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. 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? (Round your intermediate calculations and final answer to 2 decimal places.)
