Final answer:
The reciprocal services method is used to allocate support department costs based on the services provided to other departments. The total costs from the Security Department that should be allocated to the Cafeteria Department is $9,000.
Step-by-step explanation:
The reciprocal services method is used to allocate support department costs based on the services provided to other departments. In this case, the Cafeteria and Security departments support the production departments of Blue Africa Inc. To allocate the total costs from the Security Department to the Cafeteria Department, we need to calculate their reciprocal service percentages.
The reciprocal service percentage for the Security Department is calculated as the Security Department cost divided by the total department costs (Security Department cost + Cafeteria Department cost). The reciprocal service percentage for the Cafeteria Department is calculated as the Cafeteria Department cost divided by the total department costs.
Once the reciprocal service percentages are calculated, we can allocate the total costs from the Security Department to the Cafeteria Department by multiplying the reciprocal service percentage for the Security Department by the total cost of the Security Department. The total costs from the Security Department allocated to the Cafeteria Department should be $9,000.
