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 $ 70,000 Variable expenses 38,500 Contribution margin 31,500 Fixed expenses 23,310 Net operating income $ 8,190

1.If the variable cost per unit increases by $1, spending on advertising increases by $1,600, and unit sales increase by 220 units, what would be the net operating income?

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

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

4.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 $23,310 and the total fixed expenses are $38,500. Under this scenario and assuming that total sales remain the same, what is the degree of operating leverage?

5. Assume that the amounts of the companys total variable expenses and total fixed expenses were reversed.
