Mayhem Electronics makes game consoles in three processes: assembly, programming, and packaging. Direct materials are added at the beginning of the assembly process. Conversion costs are incurred evenly throughout the process. The Assembly Department had no Work-in-Process Inventory on March 31. In mid-April, Mayhem Electronics started production on 99,000 game consoles. Of this number, 95,000 game consoles were assembled during April and transferred out to the Programming Department. The April 30 Work-in-Process Inventory in the Assembly Department was 45% of the way through the assembly process. Direct materials costing \(301,950 were placed in production in Assembly during April, direct labor of \)100,960 was assigned, and manufacturing overhead of $136,200 was allocated to that department.

Requirements

1. Prepare a production cost report for the Assembly Department for April. The

company uses the weighted-average method.

2. Prepare a T-account for Work-in-Process Inventory—Assembly to show its activity during April, including the April 30 balance.

Question: Why is the calculation of equivalent units of production needed in a process costing system?

The Finishing Department started the month with 500 units in process, received 2,000 units from the Assembly Department, and transferred 2,100 units to the finished goods storage area. All direct materials are added at the beginning of the process. The units in process at the end of the month are 45% complete concerning conversion costs. The department uses the weighted-average method. The Finishing Department incurred the following costs:

8. How many units are still in process at the end of the month?

9. Compute the equivalent units of production for the Finishing Department.

10. Determine the cost per equivalent unit for transfer, direct materials, and conversion costs.

11. Determine the cost to be transferred to Finished Goods Inventory.

Billy Davidson operates Billy’s Worm Farm in Mississippi. Davidson raises worms for fishing. He sells a box of 20 worms for \(12.60. Davidson has invested \)400,000 in the worm farm. He had hoped to earn a 24% annual rate of return (net income divided by total assets), which works out to a 2% monthly return on his investment. After looking at the farm’s bank balance, Davidson fears he is not achieving this return. To evaluate the farm’s performance, he prepared the following production cost report. The Finished Goods Inventory is zero because the worms ship out as soon as they reach the required size. Monthly operating expenses total \(2,000 (in addition to the costs below).

Billy Davidson has the following questions about the farm’s performance during June.

1. What is the cost per box of worms sold? (Hint: This is the unit cost of the boxes completed and shipped out of brooding.)

2. What is the gross profit per box?

3. How much operating income did Billy’s Worm Farm make in June?

4. What is the return on Davidson’s investment of \(400,000 for the month of

June? (Compute this as June’s operating income divided by Davidson’s \)400,000

investment, expressed as a percentage.)

5. What monthly operating income would provide a 2% monthly rate of return?

What sales price per box would Billy’s Worm Farm have had to charge in June to

achieve a 2% monthly rate of return?

Roan Paper Co. produces the paper used by wallpaper manufacturers. Roan’s four-stage process includes mixing, cooking, rolling, and cutting. On March 1, the Mixing Department had 300 rolls of paper in process. During March, the Mixing Department completed the mixing process for those 300 rolls and also started and completed the mixing process for an additional 4,200 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 compiledthe following data for March:
