A customer has requested that Daleske Corp. fill a special order for 2000 units of product D84 for $20.30 a unit. While the product would be modified slightly for the special order, product D84's normal unit product cost is $18.50.

Direct materials = $6.80

Direct Labor = $3.40

Variable Manufacturing Overhead = $7.00

Fixed Manufacturing Overhead = $1.30

Unit Product cost = $ 18.50

Direct labor is a variable cost. The special order would have no effect on the company's total fixed manufacturing overhead costs. The customer would like modifications made to product D84 that would increase the variable costs by $2.50 a unit and that would require an investment of $7,000 in special molds that would have no salvage value. The special order would have no effect on the company's other sales. The company has ample spare capacity for producing the special order. If the special order is accepted, the company's overall net operating income would increase(decrease) by...($14,900), ($5,800), $3,600, or ($8,400)
