17-42 FIFO method (continuation of 17-41). 17-41 Weighted average method. McKnight Handcraft is a manufacturer of picture frames for large retailers. Every picture frame passes through two departments: the assembly department and the finishing department. This problem focuses on the assembly department. The process- costing system at McKnight has a single direct-cost category (direct materials) and a single indirect-cost category conversion costs). Direct materials are added when the assembly department process is 10% complete. Conversion costs are added evenly during the assembly department's process. McKnight uses the weighted average method of process costing. Consider the following data for the assembly department in April 2017: Required: 1.
