Willow Corp uses a process costing system in which direct materials are added at the beginning of the process and conversion costs are incurred uniformly throughout the process. Beginning inventory for January consisted of 1,250 units that were 65% completed. 9,000 units were started into the process during January. On January 31, the inventory consisted of 300 units that were 60% completed. What would be the equivalent units for direct materials cost using the weighted average method?
