Problem Five
The SCU uses 10 units of part JR63 each month in the production of radar equipment. The cost of
manufacturing one unit of JR63 is the following:

Material handling represents the direct variable costs of the Receiving Department that are applied to direct materials and purchased components on the basis of their cost. This is a separate charge in addition to manufacturing overhead. The SCU' annual manufacturing overhead budget is one-third variable and two-thirds fixed. Scott Supply, one of SCU' reliable vendors, has offered to supply part number JR63 at a unit price of $15,000.
Required：

1. If SCU purchases the JR63 units from Scott, the capacity SCU used to manufacture these parts would be idle. Should SCU decide to purchase the parts from Scott, the unit cost of JR63 would increase (or decrease) by what amount?
