Answer to Problem 30E
The total cost allocation is $40,000 and $32,000 for machining and assembly, and there is no cost allocation in maintenance and cafeteria.
Explanation of Solution
Step method:
Step method allows the allocation of the cost to the production department and service departments. Unlike the direct method, it also allocates the cost of the service to various service departments. Allocation of the cost starts from the department that has provided the highest proposition of service to the department that has provided the least service. Step method allows only one-way allocation of cost among service departments.
Calculate the cost allocation based on the step method:
Particular | Maintenance | Cafeteria | Machining | Assembly |
Service department cost | $40,000 | $32,000 | ||
Maintenance | $ (40,000) | $8,000 (1) | $20,000 (1) | $12,000 (1) |
Cafeteria | $(40,000)(4) | $20,000(2) | $20,000(3) | |
Total cost allocation | $0 | $0 | $40,000 | $32,000 |
Table: (1)
Thus, the total cost allocation is $40,000 and $32,000 for machining and assembly, and there is no cost allocation in maintenance and cafeteria.

Answer to Problem 30E
The total cost allocation is $44,200 and $27,800 for machining and assembly, and there is no cost allocation in maintenance and cafeteria.
Explanation of Solution
Cost allocation:
Cost allocation refers to the process of distributing the common cost of the production and service rendered to the various departments of the business. It is used to calculate the actual cost attributed to a specific department.
Calculate the cost allocation based on the step method:
Particular | Maintenance | Cafeteria | Machining | Assembly |
Service department cost | $32,000 | $40,000 | ||
Maintenance | $ (32,000) | $25,600(4) | $3,200(4) | $3,200(4) |
Cafeteria | $(65,600)(7) | $41,000(5) | $24,600(6) | |
Total cost allocation | $0 | $0 | $44,200 | $27,800 |
Table: (2)
Thus, the total cost allocation is $44,200 and $27,800 for machining and assembly, and there is no cost allocation in maintenance and cafeteria.
Working note 4:
Calculate the cafeteria cost allocation:

Cost allocation |
Cafeteria | 80% | $32,000 | $25,600 |
Machining | 10% | $32,000 | $3,200 |
Assembly | 10% | $32,000 | $3,200 |
