In: Accounting
Midland Resources has two production departments (Fabrication and Assembly) and three service departments (Engineering, Administration, and Maintenance). During July, the following costs and service department usage ratios were recorded.
Supplying Department | Using Department | ||||||||||||||
Engineering | Administration | Maintenance | Fabrication | Assembly | |||||||||||
Engineering | 0 | 40 | % | 0 | 15 | % | 45 | % | |||||||
Administration | 20 | % | 0 | 25 | % | 45 | % | 10 | % | ||||||
Maintenance | 0 | 30 | % | 0 | 15 | % | 55 | % | |||||||
Direct cost | $ | 42,000 | $ | 248,550 | $ | 45,000 | $ | 230,000 | $ | 80,000 | |||||
Required:
Allocate the service department costs to the two operating departments using the reciprocal method. (Matrix algebra is not required because there are only two service departments.) (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations. Round your final answers to the nearest whole dollar amounts.)

Answer:
The equations to calculate the values for administration, engineering and maintenance are as follows:
Administration = 248,550 + 40%*Engineering + 30%*Maintenance
Engineering = 42,000 + 20%*Administration
Maintenance = 45,000 + 25%*Administration
Now, we can substitute the equation for engineering and maintenance in the equation for administration, we get,
Administration = 248,550 + 40 %*( 42,000 + 20%*Administration) + 30%*(45,000 + 25%*Administration)
Solving equation, we get,
Administration = 248,550 + 16,800 + .08*Administration + 13,500 + .075*Administration
.845*Administration = 278,850
Administration = $330,000
Now, we can calculate the values for engineering and maintenance as follows:
Engineering = 42,000 + 20%*330,000 = $108,000
Maintenance = 45,000 + 25%*330,000 = $127,500
