The total cost of the 1,920 units of beginning inventory that were completed during the period is $46,760.
The total cost of the 1,920 units of beginning inventory that were completed during the period is $46,760.
The unit cost computation is $46,760 / 1,920 units = $24.35 per unit.
To compute the total cost of the 1,920 units of beginning inventory that were completed during the period:
Compute the equivalent units of production (EUP) for the beginning inventory.
Since the beginning inventory units are 25% completed, then the EUP for the beginning inventory is 25% * 1,920 units = 480 units.
Compute the total EUP for the period.
Since 12,600 units were completed during the period, and 1,600 units were 20% completed at the end of the period, then the total EUP for the period is 12,600 units + (20% * 1,600 units) = 12,880 units.
Compute the cost per equivalent unit (CPEU).
Since the total costs added during the period is $222,480 and the total EUP for the period is 12,880 units, then the CPEU is $222,480 / 12,880 units = $17.25 per unit.
Compute the total cost of the 1,920 units of beginning inventory that were completed during the period.
Since the CPEU is $17.25 per unit and the EUP for the beginning inventory that were completed during the period is 480 units, then the total cost of the 1,920 units of beginning inventory that were completed during the period is $17.25 per unit * 480 units = $46,760.
Therefore, the total cost of the 1,920 units of beginning inventory that were completed during the period is $46,760.
