EXERCISE 4-12 Calculating Equivalent Units: Weighted Average Cost Method and FIFO Method [LO3-CC11; L05 - CC16] Last month, the Finishing Department of Rohirrim Inc. started 12.000 units into production. The department had 3,600 units in process at the beginning of the month and these units were 50% complete with respect to conversion costs. There were 4,800 units in process at the end of the month, and these units were 40% complete with respect to conversion costs. A total of 10.800 units were completed and transferred to the next department during the month. Required: 1. For the last month, compute the equivalent units for conversion using the weighted average cost method. 2. Using the answer to Requirement (I). calculate the equivalent units for conversion using the FIFO method
