Hi I am looking for help on the solution to the Accounting Principles 12th edition Chapter 21 question WP21. I am confused on how to start the solution.

WP21

(This is a continuation of the Waterways Problem from Chapters 19 and 20).

Because most of the parts for its irrigation systems are standard, Waterways handles the majority of its manufacturing as a process cost system. There are multiple process departments. Three of these departments are the Molding, Cutting, and Welding departments. All items eventually end up in the Package department which prepares items for sale in kits or individually.

The following information is available for the Molding department for January.

Work in process beginning:

Units in process	24,000
Stage of completion for materials	80%
Stage of completion for labor and overhead	30%

Costs in work in process inventory:

Materials	$ 168,360
Labor	$ 67,564
Overhead	$ 16,892
Total costs in beginning work in process:	$ 252,816

Units started into production in January	60,000
Units completed and transferred in January	58,000

Costs added to production:

Materials	$265,450
Labor	$289,468
Overhead	$60,578
Total costs added into production in January:	$615,496

Work in process ending:

Units in process	26,000
Stage of completion for materials	50%
Stage of completion for labor and overhead	10%

Instructions

(a) Prepare a production cost report for Waterways using the weighted-average method.
