Chapter 4, Problem 4.36P

Job costing, accounting for manufacturing overhead, budgeted rates. The Solomon Company uses a job-costing system at its Dover, Delaware, plant. The plant has a machining department and a finishing department. Solomon uses normal costing with two direct-cost categories (direct materials and direct manufacturing labor) and two manufacturing overhead cost pools (the machining department with machine-hours as the allocation base and the finishing department with direct manufacturing labor costs as the allocation base). The 2017 budget for the plant is as follows:

	Machining Department	Finishing Department
Manufacturing overhead costs	$10,660,000	$8,000,000
Direct manufacturing labor costs	$ 970,000	$4,000,000
Direct manufacturing labor-hours	26,000	160,000
Machine-hours	205,000	31,000

1. 1. Prepare an overview diagram of Solomon’s job-costing system.

  Required

1. 2. What is the budgeted manufacturing overhead rate in the machining department? In the finishing department?
2. 3. During the month of January, the job-cost record for Job 431 shows the following:

	Machining Department	Finishing Department
Direct materials used	$16,150	$3,000
Direct manufacturing labor costs	$ 350	$1,300
Direct manufacturing labor-hours	30	50
Machine-hours	150	20

  Compute the total manufacturing overhead cost allocated to Job 431.

1. 4. Assuming that Job 431 consisted of 400 units of product what is the cost per unit?

	Machining Department	Finishing Department
Manufacturing overhead incurred	$13,250,000	$8,400,000
Direct manufacturing labor costs	$ 1,000,000	$4,300,000
Machine-hours	250,000	30,000

1. 5. Compute the under- or overallocated manufacturing overhead for each department and for the Dover plant as a whole.
2. 6. Why might Solomon use two different manufacturing overhead cost pools in its job-costing system?
