Final answer:
To assign the costs of the maintenance department to user departments based on actual usage, use the two rates and calculate the total charge. For example, if Department A uses 80% of the maintenance services and Department B uses 20%, you can charge 80% of the total maintenance costs to Department A and 20% to Department B.
Step-by-step explanation:
To assign the costs of the maintenance department to the user departments based on actual usage, you can use the two rates. Let's say there are two user departments: Department A and Department B. If Department A uses 80% of the maintenance services, and Department B uses 20%, you can assign 80% of the total maintenance costs to Department A and 20% to Department B.
For example, if the total maintenance costs for the year are $100,000, Department A would be charged $80,000 and Department B would be charged $20,000.
To calculate the total amount charged for maintenance for the year, simply add up the amounts charged to each user department.
