Job costing, accounting for manufacturing overhead, budgeted rates. The Carlson Company uses a job-costing system at its Dover, Delaware, plant. The plant has a machining department and a finishing department. Carlson 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 2012 budget for the plant is as follows:
$$
\begin{array}{l|r|r}
\hline & \text { Machining Department } & \text { Finishing Department } \\
\hline \text { Manufacturing overhead costs } & \$ 9,870,000 & \$ 7,644,000 \\
\text { Direct manufacturing labor costs } & \$ 980,000 & \$ 3,900,000 \\
\text { Direct manufacturing labor-hours } & 32,000 & 170,000 \\
\text { Machine-hours } & 210,000 & 33,000 \\
\hline
\end{array}
$$
1. Prepare an overview diagram of Carlson's job-costing system.
2. What is the budgeted manufacturing overhead rate in the machining department? In the finishing department?
3. During the month of January, the job-cost record for Job 431 shows the following:
$$
\begin{array}{l|r|r}
\hline & \text { Machining Department } & \text { Finishing Department } \\
\hline \text { Direct materials used } & \$ 13,000 & \$ 3,500 \\
\text { Direct manufacturing labor costs } & \$ 700 & \$ 1,450 \\
\text { Direct manufacturing labor-hours } & 20 & 60 \\
\text { Machine-hours } & 110 & 15 \\
\hline
\end{array}
$$
Compute the total manufacturing overhead cost allocated to Job 431 .
4. Assuming that Job 431 consisted of 100 units of product, what is the cost per unit?
5. Actual amounts at the end of 2012 are as follows:
$$
\begin{array}{l|r|r}
\hline & \text { Machining Department } & \text { Finishing Department } \\
\hline \text { Manufacturing overhead incurred } & \$ 11,380,000 & \$ 8,628,000 \\
\text { Direct manufacturing labor costs } & \$ 1,030,000 & \$ 4,300,000 \\
\text { Machine-hours } & 240,000 & 30,000 \\
\hline
\end{array}
$$
Compute the under- or overallocated manufacturing overhead for each department and for the Dover plant as a whole.
6. Why might Carlson use two different manufacturing overhead cost pools in its job-costing system?
