Question

Smith Paper Co. produces the paper used by wallpaper manufacturers. Smith’s four-stage process includes mixing, cooking, rolling, and cutting. On March 1, the Mixing Department had 400 rolls in process. During March, the Mixing Department completed the mixing process for those 400 rolls and also started and completed the mixing process for an additional 4,100 rolls of paper. The department started but did not finish the mixing process for an additional 500 rolls, which were 20% complete with respect to both direct materials and conversion work at the end of March. Direct materials and conversion costs are incurred evenly throughout the mixing process. The Mixing Department compiled the following data for March:

	Direct materials	Direct labor	Manufacturing overhead allocated	Total costs
Beginning inventory, Mar. 1	\(475	\)275	\(300	\)1,050
Costs added during March	5,045	2,900	2,965	10,910
Total costs	\(5,520	\)3,175	\(3,265	\)11,960

Requirements

1. Prepare a production cost report for the Mixing Department for March. The company uses the weighted-average method.

2. Journalize all transactions affecting the company’s mixing process during March. Assume labor costs are accrued and not yet paid.

Short answer

1. Production cost report

Step-by-step solution

Step-by-Step Solution:Step 1: Production Cost Report

A production cost report is a report which shows the direct material, conversion cost and the total cost of a product. It is mainly prepared by companies with a certain number of production processes.

Equivalent unit of production for direct material

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{material}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIPunits}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{4}\mathbf{,}\mathbf{500}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{500}\mathbf{\times }\mathbf{20}\mathbf{\%}) \\ \mathbf{=}\mathbf{4}\mathbf{,}\mathbf{600} \end{gathered}$$

Equivalent unit of production for conversion costs

$$\begin{gathered} \mathbf{EUP}\mathbf{}\mathbf{for}\mathbf{}\mathbf{Conversion}\mathbf{}\mathbf{cost}\mathbf{=}(\mathbf{Completed}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%})\mathbf{+}(\mathbf{Ending}\mathbf{}\mathbf{WIP}\mathbf{}\mathbf{units}\mathbf{\times }\mathbf{Completion}\mathbf{\%}) \\ \mathbf{=}(\mathbf{4}\mathbf{,}\mathbf{500}\mathbf{\times }\mathbf{100}\mathbf{\%})\mathbf{+}(\mathbf{500}\mathbf{\times }\mathbf{20}\mathbf{\%}) \\ \mathbf{=}\mathbf{4}\mathbf{,}\mathbf{600} \end{gathered}$$
