Show the T-account for Nash's WIP Inventory reflecting all of the appropriate costs above. Assuming Nash uses the FIFO method of process costing, complete Step 4 to determine its cost per equivalent unit for both DM and conversion costs. (Round cost per equivalent unit answers to 2 decimal places, e.g. 15.25.) Are beginning WIP Inventory costs included in these calculations? The beginning WIP Inventory costs included in the cost per equivalent unit calculations. Assuming Nash instead uses the weighted-average method of process costing, complete Step 4 to determine its cost per equivalent unit for both DM and conversion costs. (Round cost per equivalent unit answers to 2 decimal places, e.g. 15.25.) Are beginning WIP Inventory costs included in these calculations? The beginning WIP Inventory costs included in the cost per equivalent unit calculations
