Question 4 Breathe Better ("BB") manufactures diffusers for essential oils. Its main product is a diffuser that also functions as a night light called Moon Beam. BB uses First-in-First-out (FIFO) process costing. Moon beam units are produced in a two-step process in two departments: moulding and electrical. Plastic diftser moulds are made in the moulding department and transferred to the electrical department at the beginning of each month. In the electrical department, all other components are added at the start Of the manufacturing process. Conversion costs are incurred evenly throughout the manufacturing process. Inspection takes place when the production is 1000/0 complete. All spoiled products are discarded. Currently normal spoilage cost is charged to COGS at the end of each month and abnormal spoilage treated as a loss. The completed diffusers that passed the insixction are transferred to storage till they are sold and shipped to In the electrical department, there were 2,000 units of moon beam diffusers in the beginning work-in-process (WIP) at the beginning of April 2021. These diffusers were complete. At the end of April 2021, there were 3,000 units of moon beam diffusers in WIP that were 30% complete. During April 2021, 44,000 moon beam units were started. At the end of April, 39,480 completed units of moon beam were transferred to storage. Normal spoilage is set at 3% of inspected products. The following table summarises the cost of beginning WIP and new costs incurred in electrical department for April 2021: Transferred in cost Tl Direct material Conversion costs Total Required: Beginning WIP @ I April 2021 Electrical S14.OOO 10.000 3.600 27600 Current cost incurred for April 2021 in Electrical S352.ooo 220.000 170,800 742 800 (a) (b) Use FIFO process costing to calculate cost for completed, spoiled, end WIP units of moon beam diffusers in electrical department and cost per moon beam diffuser (nearest cent) for April 2021 (clearly show the costs per equivalent unit to the nearest 2 decimal place for each cost category). ( 19 marks) Based on information for April 2021 , prepare necessary journal entries to record the costs related to material, conversion costs, transferred in material, completed diffusers and abnormal loss (if any) incurred (show workings where relevant; narrations are not required).
