Question

Quizplus · Accepted Answer

Under the weighted average method, equivalent units for materials are calculated based on the units completed and transferred out plus the equivalent units in ending inventory. Since materials are added when units are 80% complete, only the ending inventory contributes to equivalent units for materials. Therefore, equivalent units = (100,000 units completed) + (15,000 units in ending inventory * 0% for materials) = 100,000 units.
