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%

b. a single paragraph.

a paragraph is a series of sentences that are organized and make sense, and are all related to a single topic . almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. this is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus the reader see the organization of the essay into subjects in order to be able to understand its main points.
