JJ Sandwiches uses the weighted average method in its process costing system. The Finishing Department is the second department irrits two-department sequential production process. In this department, all materials are added when the sandwiches are 70% complete, but conversion costs are incurred uniformly throughout the process. If there are 5,000 sandwiches in ending WIP inventory that are 45% of the way through the production process, it would be correct to say that: a there are 2,250 equivalent units in ending WIP with respect to transferred-in costs b. there are 5,000 equivalent units in ending WIP with respect to transferred-In costs. there 3,500 equivalent units in ending WIP with respect to transferred-in costs. there are zero equivalent units in ending WIP with respect to transferred-in costs
