Han Products manufactures 35,000 units of part S-6 each year for use on its production line. At this level of activity, the cost per unit for part S-6 is:
| Direct materials | $ | 3.90 | 
| Direct labor | 12.00 | |
| Variable manufacturing overhead | 2.10 | |
| Fixed manufacturing overhead | 9.00 | |
| Total cost per part | $ | 27.00 | 
An outside supplier has offered to sell 35,000 units of part S-6 each year to Han Products for $23 per part. If Han Products accepts this offer, the facilities now being used to manufacture part S-6 could be rented to another company at an annual rental of $85,000. However, Han Products has determined that two-thirds of the fixed manufacturing overhead being applied to part S-6 would continue even if part S-6 were purchased from the outside supplier.
