The Managers of Conch, Inc

The managers of Conch, Inc. want to determine the most accurate allocation of support department costs to operating departments. To make this allocation, the accounting department has collected the following data: Services Provided By
Computer Cafeteria
Direct costs $55,000 $35,000
Service provided to:
Computer department ---- 15%
Cafeteria 10% ----
Operating department 1 50% 40%
Operating department 2 40% 45%
If the reciprocal method is used, the equation representing the total cost of the computer department is:

A) Computer costs = $55,000 + (0.15 × cafeteria cost)
B) Computer costs = $55,000 + (0.10 × cafeteria cost)
C) Computer costs = $55,000
D) Computer costs = $55,000 + 0.10 × ($55,000 + 0.10 × computer cost)
