Jergis and Daughters produces goods in three departments: Cutting, Assembly, and Packaging. This period, 4,000 units were transferred from Cutting to Assembly, and 4,500 were transferred from Assembly to Packaging. The Assembly department worked on a total of 5,000 units, 200 of which ended up spoiled. Normal spoilage in the Assembly department is 2% of good output. Calculate total units, how they started, and how they ended up for Assembly, using first the weighted average method, then the FIFO method.
