Tiny Packs produces leather backpack purses that it markets to working professionals looking for an alternative to a briefcase or standard purse. Tiny Packs' products originate in the Cutting department, and they are then put together in the Assembly department. At the conclusion of the assembly process, each backpack is subject to a short inspection before being packaged for sale. The following unit information was compiled to reflect activity in the Assembly department for the most recent month of August:

b. What is the cost of units transferred out and the cost of ending WIP using the Weighted-Average method? (5 pts)

c. What is the gross margin percentage under both FIFO and Weighted-Average? Which method should Tiny consider implementing? (4 pts)
