Ending WIP, May 31	25,000	18,000
Total units accounted for	115,000	100,000

On May 31, the Mixing Department ending Work-in-Process Inventory was 80%

complete for materials and 45% complete for conversion costs. The Heating Department ending Work-in-Process Inventory was 60% complete for materials and 35% complete for conversion costs. The company uses the weighted-average method. Requirements

1. Compute the equivalent units of production for direct materials and for conversion costs for the Mixing Department.

2. Compute the equivalent units of production for transferred in costs, direct materials, and conversion costs for the Heating Department.

Step by step solution

01

Step-by-Step Solution:Step 1: Equivalent Unit of Production

The equivalent unit of production is calculated by multiplying the number of units with the completion percentage. The Equivalent unit of production for direct material is the aggregate of the equivalent unit completed unit and the equivalent units of WIP units.

02

Equivalent unit of production for direct materials for the mixing department

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{material}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIPunits}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{90}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{25}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{80}\mathbf{\%}) \\ \mathbf{=}\mathbf{110}\mathbf{,}\mathbf{000} \end{gathered}$$

03

Equivalent unit of production for conversion costs for the mixing department

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{Conversion}\mathbf{}\mathbf{costs}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIPunits}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{90}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{25}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{45}\mathbf{\%}) \\ \mathbf{=}\mathbf{101}\mathbf{,}\mathbf{250} \end{gathered}$$

04

Equivalent unit of production for direct materials for the heating department

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{material}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIPunits}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{82}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{18}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{60}\mathbf{\%}) \\ \mathbf{=}\mathbf{92}\mathbf{,}\mathbf{800} \end{gathered}$$

05

Equivalent unit of production for conversion costs for the heating department

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{Conversion}\mathbf{}\mathbf{costs}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIPunits}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{82}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{18}\mathbf{,}\mathbf{000}\mathbf{\times }\mathbf{35}\mathbf{\%}) \\ \mathbf{=}\mathbf{88}\mathbf{,}\mathbf{300} \end{gathered}$$
