The Bottling Department of Mountain Springs Water Company had $4,700$ liters in beginning work in process that were $20\%$ complete. During the period, $57,800$ liters were completed. The ending work in process inventory had $3,100$ liters that were $55\%$ complete. Assume that Mountain Springs uses the FIFO cost flow method and that materials are added at the beginning of the process. What are the conversion equivalent units of production for the period?
