Required:1. Prepare a physical flow schedule.2. Calculate equivalent units of production.3. Compute unit cost.4. Calculate the cost of goods transferred to Finishing at the end of the month. Calculate the cost of ending inventory.5. Assume that the masks are inspected at the end of the molding process. Of the 18000 units inspected 1000 are rejected as faulty and are discarded. Thus only 17000 units are transferred to the finishing department. The manager of Yomasca considers all such spoilage as abnormal and does not want to assign any of this cost to the 17000 good units produced and transferred to finishing. Your task is to determine the cost of this spoilage of 1000 units and then to discuss how you would account for this spoilage cost. Now suppose that the manager feels that this spoilage cost is just part of the cost of producing the good units transferred out. Therefore he wants to assign this cost to the good production. Explain how this would be handled.
