13 Delta Company produces a single product. The cost of producing and selling a single unit of this product at the company's normal activity level of 60,000 units per year is: Direct materials $5.10 Direct labor 3.80 Variable overhead 1.00 Fixed overhead 4.20 Variable selling and administrative expense 1.50 The normal selling price is $21 per unit. The company's capacity is 75,000 units per year. An order has been received from a mail-order house for 15,000 units at a special price of $14 per unit. This order would not disturb regular sales. Question: If the order is accepted, by how much will annual profits be increased or decreased? (The order will not change the company's total fixed costs.) Refer to the data above. Assume the company has 1,000 units of this product left over from last year that are vastly inferior to the current model. The units must be sold through regular channels at reduced prices. What unit cost figure is relevant for establishing a minimum selling price for these units? Explain
