I am having difficulty with the calculations of this problem, can someone show me a step-by-step way to calculate this?

Ferdon Watches, Inc., makes four models of watches, Gag-Gift, Commuter, Sport, and Retirement. Ferdon manufactures the watches in four departments: Assembly, Polishing, Special Finishing, and Packaging. All four models are started in Assembly where all material is assembled. The Gag-Gift is transferred to Packaging, where it is packaged and transferred to finished goods inventory. The Commuter and Sport are assembled, then transferred to Polishing. Once the polishing process is completed, they are transferred to Packaging and then finished goods. The Retirement model is assembled and then transferred to Special Finishing, and then Packaging. When packaged, it is transferred to finished goods.

Data for October are shown in the following table. Conversion costs are allocated based on the number of units processed in each department.
