Edward Company uses the FIFO method in its process costing system. The first processing department, the Welding Department, started the month with 10,000 units in its beginning work in process inventory that were 40% complete with respect to conversion costs. The conversion cost in this beginning work in process inventory was $12,800. An additional 94,000 units were started into production during the month. There were 14,000 units in the ending work in process inventory of the Welding Department that were 80% complete with respect to conversion costs. A total of $286,740 in conversion costs were incurred in the department during the month. What would be the cost per equivalent unit for conversion costs? A)2.88 B) 3.2 C) 2.95 I know answer is C. I know how to get it. But what is that $12,800 in beginning work in process??? Thatgot me little confused... Because that$12,800 has nothing to do with getting the cost per equivalent unit. I am thinking $12,800 is how much those 10,000 units actually cost??
