wolverine [178]

Using the weighted average method, the equivalent units to be considered would only be that which is completed within the month and those completed in the ending inventory. Since the ending inventory is only ¼ or 25% completed, therefore the total equivalent units is:

total equivalent units = 127,500 units + (0.25)*40,000 units

total equivalent units = 137,500 units

 

Since the direct labor costs is given to be $24,000 therefore the direct labor cost per equivalent unit is:

direct labor cost per equivalent unit = $24,000 / 137,500 units

direct labor cost per equivalent unit = $0.1745 

<span>direct labor cost per equivalent unit </span>= $0.17

 

Answer:

$0.17
