assume the following information: milling department materials conversion total cost of beginning work in process inventory $ 10,000 $ 15,000 $ 25,000 costs added during the period 291,600 385,000 676,600 total cost $ 301,600 $ 400,000 $ 701,600 assume the equivalent units of production for materials and conversion are 5,200 units and 5,000 units, respectively, using the weighted-average method. if 4,620 units were completed and transferred to the next department, then what is the total cost of the ending work in process inventory in the milling department?
