Direct materials $1.30

The normal selling price is $12 per unit. The companys capacity is 20,000 units per year. An order has been received from a mail-order house for 5,000 units at a special price of $6 per unit. This order would not disturb regular sales. If the order is accepted, by how much will annual profits be increased or decreased? (The order will not change the companys total fixed costs.)

What unit cost figure is relevant for establishing a minimum selling price for these units? a. $4.30 b. $ .50 c. $5.25 d. none of the costs are relevant
