Zear Company produces an electronic processor and sells it wholesale to manufacturing and retail outlets at $10 each. In Zear's Year 8 fiscal period, it sold 500,000 processors. Fixed costs for Year 8 total $1,500,000, including interest costs on its 7.5% debentures. Variable costs are $4 per processor for materials. Zear employs about 20 hourly paid plant employees, each earning $35,000 in Year 8.

Zear is currently confronting labor negotiations. The plant employees are requesting substan- tial increases in hourly wages. Zear forecasts a 6% increase in fixed costs and no change in either the processor's price or in material costs for the processors. Zear also forecasts a 10% growth in sales volume for Year 9. To meet the necessary increase in production due to sales demand, Zear recently hired two additional hourly plant employees.
