Collaborative Learning Problem 17-42 Standard-costing method. Ozumo's Gardening makes several different kinds of mulch. Its busy period is in the summer months. In August, the controller suddenly quit due to a stress-related disorder. He took with him the standard costing results for RoseBark, Ozumo's highest quality mulch. The controller had already completed the assignment of costs to finished goods and work in process, but Ozumo does not know standard costs or the completion levels of inventory. The following information is available: Physical and Equivalent Units for RoseBark For the Month Ended August 31, 2012 Equivalent Units (yards) Physical Units Direct Conversion (Yards of Mulch) Materials Costs Completion of beginning work in process 965,000 434,250 Started and completed 845,000 845,000 845,000 Work on ending work in process 1,817,000 1,817,000 1,090,200 2,662,000 2,369,450 Units to account for 3,627,000 Cost of units completed from beginning work in process Cost of new units started and completed Cost of units completed in August Cost of ending work in process Total costs accounted for Costs $ 7,671,750 6,717,750 14,389,500 12,192,070 $26,581,570 RE 1.
