X Company is considering buying a part next year that they currently make. This year's total production costs for 3,200 units of this part were:
Materials $8,480
Direct labor [all variable] 11,520
Variable overhead 13,120
Fixed overhead 13,120
Total $46,240
1. If production next year is expected to be 3,600 units, how much can X Company save by buying the part instead of making it?
