Real Pen Company ("RP") manufactures fancy pens and uses process costing. One of its products - Bunny - is manufactured in department X. All material and conversion costs are added evenly throughout the process. Bunny pens are inspected at the 80% point. If the pen does not pass the inspection, it is discarded. At the end of the process, good pens are transferred to the warehouse for safe keeping.

There were 30,000 Bunny pens in work-in-process (WIP) at the beginning of May 2018. These pens were 30% complete. At the end of May 2018, there were 12,000 Bunny pens in the WIP in department X and the pens were 50% complete. During May 2018, 200,000 Bunny pens were started. At the end of May, 208,000 completed pens were transferred to the warehouse. Normal spoilage is set at3% of inspected products.The following table summarises the cost of beginning WIP and new costs incurred in department X for May 2018:
