#!# 15-22B. (Fixed costs) Sausalito Silkscreen is forecasting fixed costs next year of $375,000. The firm's single product sells for $25 per unit and incurs a variable cost per unit of $13. The finn may acquire some new binding equipment that would lower variable cost per unit to $11. The new equipment, however, would add to fixed costs through the price of an annual maintenance agreement on the new equipment. Ho~ large can this increase in fixed costs be and still keep the firm's present break-even point in units produced and sold unchanged?
