E6-1 Page 348 Computing equivalent units of production Using the data given for Cases 1 below, and assuming the use of the average cost method, compute the separate equivalent units of productionone for materials and one for labor and overhead under each of the following assumptions (labor and factory over- head are applied evenly during the process in each assumption): Assumptions: a. All materials go into production at the beginning of the process Case 2Opening inventory 5,000 units, three-fifths completed; started in process 40,000 units; finished 39,000 units; work in pro- cess, end of period, 6,000 units, one-fourth completed. For this problem, determine the equivalent units for materials only.
