Harmony is currently producing 100 units of a necessary component part by incurring $60,000 in direct materials, $12,500 in direct labor, $22,500 in variable overhead, and $15,000 in fixed overhead. If Harmony purchases the component externally, $10,000 of fixed costs can be avoided. What is the external price for 100 units at which the company is indifferent between buying and selling?
