Weighted-Average Method 1. Equivalent units of production: Materials Conversion Transferred to next department. Equivalent units in ending work in process inventory: Materials: 40,000 units 100% complete. Conversion: 40,000 units 25% complete. Equivalent units of production. 2. Cost per equivalent unit Materials Conversion Cost of beginning work in process. Cost added during the period. Total cost (a) Equivalent units of production (b) Cost per equivalent unit (a) (b) 3. and 4. Assigning costs to units: Materials Conversion Total Ending work in process inventory: Equivalent units. Cost per equivalent unit. Cost of ending work in process inventory. Units completed and transferred out: Units transferred to the next department. Materials Conversion Total Cost per equivalent unit. Cost of units completed and transferred out. Problem 4-15 (continued) 5. Cost reconciliation: Costs to be accounted for: Cost of beginning work in process inventory Costs added to production during the period Total cost to be accounted for $623,500 Costs accounted for as follows: Cost of ending work in process inventory. Cost of units completed and transferred out Total cost accounted for. $536,000
