Is the following description true or false?

1.The contribution margin ratio can be used to quickly calculate the change in net operating income when a change in sales units is given.

2.Fixed manufacturing overhead costs are included as part of the finished goods inventory balance under the absorption costing concept.

3.If fixed costs are $850,000 and the unit contribution margin is $50, profit is zero when 15,000 units are sold.

4.For a period during which inventory units sold is less than inventory units produced, income from operations reported under variable costing will be smaller than income from operations reported under absorption costing.

5.At the break-even point, total contribution margin and fixed expenses are equal.

6.For a profitable company, when viewing the CVP graph, the Sales line will have a steeper slope than the Total Cost line.

7.Earthlings Inc started the year with 1,000 units in beginning inventory. They produced 17,800 units during the year, and sold 18,100 units. Net Operating Income is greater under Variable costing than Absorption Costing.
