Explanation:
The cost of the process is the distribution of production costs to the units of output. The key difference between the FIFO and the weighted average approach is the handling of the inventory of started work-in-process or unfinished products.
The weighted average approach incorporates this inventory computing process costs, although it is kept separate by the FIFO approach. In the weighted average process costing system, the cost is measured and applied equally to all passed out units and units in the process of closing work.
