Oster Manufacturing uses a weighted-average process costing system and has the

following costs and activity during October.

Materials $40,000

Conversion cost 32,500

Total beginning work-in-process inventory $72,500

Materials $ 700,000

Conversion cost 617,500

Total production costs - October $1,317,500

Production completed 60,000 units

Work-in-process, October 31 20,000 units

All materials are introduced at the start of the manufacturing process, and conversion cost

is incurred uniformly throughout production. Conversations with plant personnel reveal

that, on average, month-end in-process inventory is 25% complete. Assuming no

spoilage, how should Oster’s October manufacturing cost be assigned?
