X Company is considering buying a part next year that they currently make. This year's production costs for 3,200 units were:
|  | Total | Per-Unit | 
| Materials | $8,512 | $2.66 | 
| Direct labor [all variable] | 15,936 | 4.98 | 
| Variable overhead | 10,880 | 3.40 | 
| Fixed overhead | 9,920 | 3.10 | 
| Totals | $45,248 | $14.14 | 
A company has offered to supply this part for $13.38 per unit. If X Company buys the part, $4,960 of the fixed overhead can be avoided. Also if X Company buys the part, it can use the freed-up resources to increase production of another product, resulting in additional contribution margin of $2,700. Production next year is also expected to be 3,200 units.
