Super corporation produces a part in the manufactures of its product. The unit cost is $21 computed as follows:
An outside supplier has offered to provide the annual requirement of 7,200 of the parts for only $13 each. The company estimates that 60% of the fixed manufacturing overhead cost above could be eliminated if the parts are purchased from the outside supplier. Assume that direct labor is an avoidable cost in this decision. Based on these data, the financial advantage (disadvantage) of purchasing the parts from the outside supplier would be:
                                    $
Direct material                         6
Direct labour                           8
Variable manufacturing overhead         2
Fixed manufacturing overhead           5
Total cost                             21
Answer:
Total financial advantage of buying from the supplier $43,200
Explanation:
Unit relevant variable  cost of making= 6+8 +2 = 16
                                          $
Variable cost of making (  16×   7200) =       115,200   Â
Variable of buying      (13  ×7200)           93,600
Savings in variable cost                     21,600
Savings in fixed cost  (60%*72300 × 5)         21600
Total savings from buying                  43,200
 Total financial advantage of buying from the supplier $43,200
