Process Costing EUP A company started its business this year. It started 500 units into production and completed 400 units. Direct materials are added at the beginning of the process. Conversion costs are spent evenly throughout production. Ending work in process inventory was 80 % completed with respect to conversion costs. Calculate the equivalent units of production. [Single-stage Production Process] GDI is a manufacturer of military equipment. All products go through an identical manufacturing process. Process costing has a single direct-cost category (DM) and a single indirect-cost category (CC). DMs are added at the beginning of the process CCs are added evenly throughout the process. The weighted-average method is used for units and costs. Determine the cost of goods manufactured and the ending Work-In-Process DM =500 CC480 Beginning Work-In-Process Physical units 400 $120,000 Direct materials $ 36,000 Conversion costs 60% Degree of completion Started Physical units 1,000 $370,000 Direct materlals Conversion costs $168,480 Completed Physical units 1.200 Ending Work-In-Process Physical units 200 Degree of completion 40% [Two-stage Production Process] This is the continuation of the above question: the second stage production of GDI.

Determine the cost of goods manufactured and the ending Work-In-Process Standard Cost System in Process Costing] Bio-DC is a biotech company in Milpitas. It makes a cancer-treatment drug through a single processing department. Direct materials are added at the start of the process. Conversion costs are added evenly throughout the process. Bio-DC uses standard cost system in process costing: it determines the standard cost of $8.25 per equivalent unit for direct materials and $12.70 per equivalent unit for conversion costs for both beginning Work-In-Process and the work done in the current period.
