Lehman Corp. has two departments: Assembly and Testing. Assembly department had beginning inventory of 750 units which were 50% complete. During the year, 1,200 units were completed and transferred to the Testing department. Ending inventory is comprised of 800 units which were 75% complete. Compute the equivalent units of work done for conversion costs during the year for Lehman Corp. assuming it follows the FIFO process-costing method. Assume direct materials were added at the beginning of the process.
