I need this answer for this question

Assume that the masks are inspected at the end of the molding process. Of the 45,000 units inspected, 2,500 are rejected as faulty and are discarded. Thus, only 42,500 units are transferred to the finishing department. The manager of Mimasca considers all such spoilage as abnormal and does not want to assign any of this cost to the 42,500 good units produced and transferred to finishing. Your task is to determine the cost of this spoilage of 2,500 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. (Hint: Spoiled units are a type of output, and equivalent units of spoilage can be calculated.)
