a-g, explain how you found answer please

Swan Corp. began work on 3,000 units this period. Work In Process Inventory was 500 at the beginning of the period (60% complete) and 1,000 at the end of the period (50% complete). Beginning inventory costs were $3,000 for conversion costs and $7,000 for direct materials. During the period, Swan incurred $75,000 for conversion costs and $52,500 for direct materials. Swan uses the weighted average method of process costing. Direct materials are added at the beginning of the process, and conversion costs are incurred evenly throughout the period. Required: Using the weighted average method, compute: a. How many units were completed during the period? Unis Completed b. Determine the number of equivalent units for direct materials Equivalent Units c. Determine the number of equivalent units for conversion costs. Equivalent Units d. Calculate the cost per equivalent unit for direct materials. Cost per Equivalent Unit e. Determine the cost per equivalent unit for conversion costs. Cost per Equivalent Unit f. Determine the cost assigned to ending Work in Process Inventory. Ending Work in Process g. Determine the cost assigned to goods completed and transferred out. Goods Completed and Transferred Out
