Carries Limited has two departments, the assembly department and the testing department in its brake-pad manufacturing plant, where each brake-pad is conveyed through each department. Carries process-costing system consist of two cost categories: Single direct cost (direct materials) and a single indirect-cost category (conversion costs). Direct materials are added at the beginning of the process. Conversion costs are added evenly during the process. When the assembly department finishes work on each brake-pad, it is immediately transferred to testing. Carries uses the weighted-average method of process costing. Data for the assembly department for October 2019 are as follows: Physical Units (Brake Pads) Direct Materials Conversion Costs Work in process, October 1x 6,000 $1,200,000 $ 400,750 Started during October 2019 21,000 Completed during October 2019 23,500 Work in process, October 31y 3,500 Total costs added during October 2019 $4,600,000 $2,456,500 x Degree of completion: direct materials, 100%; conversion costs, 60%. y Degree of completion: direct materials, 100%; conversion costs, 70%. Required: 1. Compute equivalent units in the assembly department, for each cost category? 2. Summarize total assembly department costs for October 2019 for each cost category, and calculate the cost per equivalent unit? 3. Assign total costs to units completed and transferred out and to units in ending work in process? 4. a. By reference to the above data: a. What are the similarities between job-order and process costing? b. What are the differences between job-order and process costing?
