I am trying to fill in the last two columns for Conversion Equivalent Units.

Equivalent Units of Production The Converting Department of Worley Company had 640 units in work in process at the beginning of the period, which were 75% complete. During the period, 13,600 units were completed and transferred to the Packing Department. There were 720 units in process at the end of the period, which were 25% complete. Direct materials are placed into the process at the beginning of production. Determine the number of equivalent units of production with respect to direct materials and conversion costs. If an amount is zero, enter in "0". Worley Company Number of Equivalent Units of Production Direct Materials Conversion Whole Units Equivalent Units Equivalent Units Inventory in process, beginning 640 160 Started and completed 12,960 12,960 12,960 Transferred to Packing Department 13,600 12,960 13,120 720 720 288 X Inventory in process, ending 13,680 13,440 X Total 14,320 Feedback Check My Work When are the materials added to the units? How much more needs to be done to the beginning units with respect to conversion costs to complete the units? How much has been added to the units in ending work in process inventory with respect to materials and conversion
