17-36 Weighted-average method. Hoffman Company manufactures car seats in its Boise plant. Each

car seat passes through the assembly department and the testing department. This problem focuses on the

assembly department. The process-costing system at Hoffman Company has a single direct-cost category

(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 car seat, it is immediately transferred to testing.

Hoffman Company uses the weighted-average method of process costing. Data for the assembly department

for October 2017 are as follows:
