EXERCISE 9-9 Equivalent Units and Cost per Equivalent Unit-Weighted-Average Meth0d [L02, L03, L04] Helix Corporation produces prefabricated flooring in a series of steps carried out in production departments. All of the material that is used in the first production department is added at the beginning of processing in that department. Data for May for the first production department follow: Percent Complete Materials Conversion Units Work in process inventory, May 1. Work in process inventory, May 31 5,000 10,000 100% 100% 40% 30% Materials cost in work in process inventory, May 1 Conversion cost in work in process inventory, May 1. . . Units started into production Units transferred to the next production department.. Materials cost added during May Conversion cost added during May $1,500 $4,000 180,000 175,000 $54,000 $352,000 Required Assume that the company uses the weighted-average method of accounting for units costs. Determine the equivalent units for May for the first process 2.Compute the costs per equivalent unit for May for the first process Determine the total cost of ending work in process inventory and the total cost of units trans to the next process in May
