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	$ 50,000
Variable expenses	27,500
Contribution margin	22,500
Fixed expenses	14,850
Net operating income	$ 7,650

5. If sales decline to 900 units, what would be the net operating income?

6. If the selling price increases by $2 per unit and the sales volume decreases by 100 units, what would be the net operating income?

8. What is the break-even point in unit sales?

9. What is the break-even point in dollar sales?

10. How many units must be sold to achieve a target profit of $13,500?

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

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

14. 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 $14,850 and the total fixed expenses are $27,500. 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.)

15. 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 $14,850 and the total fixed expenses are $27,500. 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.)
