University Printers has two service departments Maintenance and Personnel and two operating departments Printing and Developing. Management has decided to allocate maintenance costs on the basis of machine-hours in each department and personnel costs on the basis of labor-hours worked by the employees in each. The following data appear in the company records for the current period:
Maintenance Personnel Printing Developing
Machine-hours ? 455 455 2,590
Labor-hours 315 ? 294 1,491
Department direct cost 11,000 $23,000 $25,000 $23,000
Required: Allocate the service department costs using the reciprocal method. Negative amounts should be indicated by a minus sign. Do not round intermediate calculations.

Machine hour percentages -Allocation of Maintenance Costs  

455 + 455 + 2,590 = 3,500 total machine hrs

Personnel = 455 / 3,500 = 13%

Printing  = 455 / 3,500 = 13%

Developing = 2,590 / 3,500 = 74%

Labor hr. percentages--Allocation of Personnel costs  

315 + 294 + 1,491 = 2,100 total labor hrs.    

Maintenance = 315 / 2,100 = 15%

Printing  = 294 / 2,100 = 14%

Developing = 1,491 / 2,100 = 71%
