Question

irkland Company manufactures a part for use in its production of hats. When 10,000 items are produced, the costs per unit are:

                     Direct materials                                                                 $0.60

                     Direct manufacturing labor                                                 3.00

                     Variable manufacturing overhead                                        1.20

                     Fixed manufacturing overhead                                          1.60

                          Total                                                                            $6.40

                                

Mike Company has offered to sell to Kirkland Company 10,000 units of the part for $6.00 per unit. The plant facilities could be used to manufacture another item at a savings of $9,000 if Kirkland accepts the offer. In addition, $1.00 per unit of fixed manufacturing overhead on the original item would be eliminated. (HINT: $.60 will NOT differ between these two alternatives.)

What is the relevant per unit cost for the original part?
