Answer:
C. In most process costing systems, direct materials are added at the beginning of the process while conversion costs are added evenly throughout the manufacturing process.
Explanation:
The equivalent unit is the unit of production that has been completed based on a percentage of completion. It is usually calculated for the conversion costs, which is added evenly throughout the period. The equivalent unit of production expresses the amount of work done on units of output that are partially completed at the end of an accounting period. Basically, the fully completed units and the partially completed units are expressed in terms of fully completed units. This helps in assigning costs to the partially completed units.
