Table Craft Concept manufactures small tables in its Processing Department. Direct materials are added at the initiation of the production cycle and must be bundled in single kits for each unit. Conversion costs are incurred evenly throughout the production cycle. Before inspection, some units are spoiled due to undetectible materials defects. Inspection occurs when units are 50% converted. Spoiled units generally constitute 8% of the good units. Data for December 2018 are as follows:
