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.

Materials ........................$168,360
Labor ........................$67,564
Overhead .......................$17,270
Total costs in beginning work in process ..........$253,194
Units started into production in January ...........$60,000
Units completed and transferred in January .........$58,000

Costs added to production:

Materials ......................$264,940

Instructions:

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

(b) Show the equivalent units for materials and conversion costs if Waterways used FIFO instead of weighted-average.
