ProcessPro is a fast-growing manufacturer of computer chips. Direct materials are added at the start of the production process. Conversion costs are added evenly during the process. Some units of this product are spoiled as a result of defects not detectable before inspection of finished goods. Spoiled units are disposed of at zero net disposal value. ProcessPro uses the FIFO method of process costing. Summary data and weighted-average data for September 2020 are as follows: Requirement 1. For each cost category, compute equivalent units. Show physical units in the first column. Enter the physical units in first, then calculate the equivalent units. (Complete all input fields. Enter a "0" for applicable zero amounts.)

For each cost category, compute equivalent units. Show physical units in the first column. 2. Summarize total costs to account for; calculate cost per equivalent unit for each cost category; and assign costs to units completed and transferred out (including normal spoilage), to abnormal spoilage, and to units in ending work in process. 3. Should Process Pro's managers choose the weighted-average method or the FIFO method? Explain.
