Q 7.24: Impala is currently producing 100 units of a necessary component part by incurring $42,000 in direct materials, $8,750 in direct labor, $15,750 in variable overhead, and $10,500 in fixed overhead. If Impala purchases the component externally, $7,000 of fixed costs can be avoided. What is the external price for 100 units at which the company is indifferent between buying and selling?
