Air Purifier Inc. computes its break-even point strictly on the basis of cash expenditures related to fixed costs. Its total fixed costs are $2,520,000, but 20 percent of this value is represented by depreciation. Its contribution margin (price minus variable cost) for each unit is $54. How many units does the firm need to sell to reach the cash break-even point? (Round your answer to the nearest whole number.)

Boise Timber Co. computes its break-even point strictly on the basis of cash expenditures related to fixed costs. Its total fixed costs are $8,300,000, but 20 percent of this value is represented by depreciation. Its contribution margin (price minus variable cost) for each unit is $27. How many units does the firm need to sell to reach the cash break-even point?

Shawn Pen & Pencil Sets Inc. has fixed costs of $421,400. Its product currently sells for $18 per unit and has variable costs of $8.20 per unit. Mr. Bic, the head of manufacturing, proposes to buy new equipment that will cost $440,000 and drive up fixed costs to $563,500. Although the price will remain at $18 per unit, the increased automation will reduce costs per unit to $5.75.
