    1) CPA Manufacturing produces electronic storage devices, and uses the following three-part classification for its manufacturing costs: direct materials, direct manufacturing labor, and indirect manufacturing costs. Total indirect manufacturing costs for January were $300 million, and were allocated to each product on the basis of direct manufacturing labor costs of each line. Summary data (in millions) for January for the most popular electronic storage device, the Harddrive, was:

    Big Bertha
    Direct manufacturing costs $9,000,000
    Direct manufacturing labor costs $3,000,000
    Indirect manufacturing costs $8,500,000
    Units produced 40,000


    a. Compute the manufacturing cost per unit for each product produced in January.

    b. Suppose production will be reduced to 30,000 units in February. Speculate as to whether the unit costs in February will most likely be higher or lower than unit costs in January; it is not necessary to calculate the exact February unit cost. Briefly explain your reasoning.

    5) CPA Manufacturing uses departmental cost driver rates to apply manufacturing overhead costs to products. Manufacturing overhead costs are applied on the basis of machine-hours in the Machining Department and on the basis of direct labor-hours in the Assembly Department. At the beginning of 20X5, the following estimates were provided for the coming year:

    Machining Assembly
    Direct labor-hours 10,000 dlh 90,000 dlh
    Machine-hours 100,000 mh 5,000 mh
    Direct labor cost $ 80,000 $720,000
    Manufacturing overhead costs $250,000 $360,000

    The accounting records of the company show the following data for Job #846:

    Machining Assembly
    Direct labor-hours 50 dlh 120 dlh
    Machine-hours 170 mh 10 mh
    Direct material cost $2,700 $1,600
    Direct labor cost $ 400 $ 900


    a. Compute the manufacturing overhead allocation rate for each department.

    b. Compute the total cost of Job #846.

    c. Provide possible reasons why CPA Manufacturing uses two different cost allocation rates.
