Assume there were 6,000 units in beginning work in process, 60% complete. 20,000 units were completed during the month. Ending work in process is 40% complete, which is equivalent to 3,200 units for conversion costs. Materials are added at the beginning of the process. The standard cost method is used. Assume that conversion costs are $122,100 for the month, and the equivalent unit cost for conversion is $5.50. The ending work in process is 80% complete, and the beginning work in process consisted of 2,000 units, 40% complete. The company completed 17,000 units. What is the number of whole units in the ending work in process under the FIFO method?A) 6,000 unitsB) 6,500 unitsC) 7,500 unitsD) 5,200 units
