Problem 4-14A Analysis of Work in Process T-account-Weighted-Average Method [LO4-1, LO4-2, LO4-3, LO4-4] Weston Products manufactures an industrial cleaning compound that goes through three processing departmentsGrinding, Mixing, and Cooking. All raw materials are introduced at the start of work in the Grinding Department. The Work in Process T-account for the Grinding Department for May is given below: Work in ProcessGrinding Department ________________________________________ ________________________________________ Inventory, May 1 21,800 Completed and transferred to the Mixing Department ? Materials 133,400 Conversion 225,500 ________________________________________ ________________________________________ Inventory, May 31 ? ________________________________________ The May 1 work in process inventory consisted of 18,000 pounds with $14,600 in materials cost and $7,200 in conversion cost. The May 1 work in process inventory was 100% complete with respect to materials and 30% complete with respect to conversion. During May, 167,000 pounds were started into production. The May 31 inventory consisted of 15,000 pounds that were 100% complete with respect to materials and 60% complete with respect to conversion. The company uses the weighted-average method to account for units and costs. Required: 1. Determine the equivalent units of production for May. Equivalent units of production. What is the material and conversion? 2. Determine the costs per equivalent unit for May. (Round your answers to 2 decimal places.) Cost per equivalent unit. What is the material and conversion? 3. Determine the cost of the units completed and transferred to the Mixing Department during May. What is the material and conversion?
