Your first task is to clear up the production records of the mixing department for November 2020. You learn that the mixing department is the last stage of the shampoo production process. Units transferred from the previous department use direct labour and overhead inputs evenly in mixing. A secret ingredient is also added to each unit at the 40% point in processing. You also find out that the beginning inventory for the month of November was 4,000 units with the following costs: Transferred-in costs Direct materials Conversion costs $ 16,000 3,600 24,000 In addition, during November, 16,000 units were transferred to mixing at a $4 unit cost. The ending inventory consisted of 5,000 units that were 60% complete. During the month, direct materials of $26,400 were added and 8,500 hours of direct labour were used at a wage rate of $12 per hour. The overhead rate for 2020, applied on a basis of direct labour hours, was based on a predicted annual usage of 120,000 hours and a cost function derived from the following overhead equation: Y = 60,000 + 2x, where Y is the total overhead costs and X is the direct labour hours. Using weighted average process costing techniques, calculate the following for the mixing department for November 2020: (a) ZYour answer has been saved and sent for grading.
