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	$	21,200
Variable expenses		12,400
Contribution margin		8,800
Fixed expenses		6,952
Net operating income	$	1,848

1 if the variable cost per unit increases by $1.40, spending on advertising increases by $1,900, and unit sales increase by 250 units, what would be the net operating income? (Do not round intermediate calculations.)

2 how many units must be sold to achieve a target profit of $5,324? (Do not round intermediate calculations.) Number of units ?

3-a.	What is the margin of safety in dollars? (Do not round intermediate calculations.)

Margin of safety?____$

3-b.	What is the margin of safety percentage? (Round your final answers to the nearest whole percentage (i.e, .12 should be entered as 12).)

Margin of safety?____%

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

5 Using the degree of operating leverage, what is the estimated percent increase in net operating income of a 4% increase in sales? Do not round intermediate calculations. Round your percentage answer to 2 decimal places (i.e .1234 should be entered as 12.34).

increase in net operating income?

6 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 $6,952 and the total fixed expenses are $12,400. 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.)

7 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 $6,952 and the total fixed expenses are $12,400. Given this scenario, and assuming that total sales remain the same, calculate the degree of operating leverage. Using the calculated degree of operating leverage, what is the estimated percent increase in net operating income of a 4% increase in sales? Do not round intermediate calculations. Round your percentage answer to 2 decimal places (i.e .1234 should be entered as 12.34).
