Answer: Process costing system.
Explanation: A process costing system used in the manufacturing industry that accumulates the costs of producing a continuous stream of similar items.
It is calculated thus:
Cost per unit = cost of unit/ expected output in unit.
Using process costing method is very efficient to accumulate costs at an aggregate level for a large batch of products and then allocate the cost to the individual units produced.
There are three types of process costing and they are:
1. Weighted Average Cost
2. FIFO - First In First Out
3. Standard Cost
