The Sendai Co., Ltd., of Japan has budgeted costs in its various departments as follows for the coming year:

Factory Administration	$	825,470
Custodial Services		108,831
Personnel		28,970
Maintenance		60,569
Machiningoverhead		633,098
Assemblyoverhead		865,282
Total cost	$	2,522,220

The company allocates service department costs to other departments in the order listed below.

Department	Number of Employees	Total Labor- Hours	Square Feet of Space Occupied	Direct Labor- Hours	Machine- Hours
Factory Administration	27		7,000
Custodial Services	10	7,200	11,900
Personnel	24	19,100	8,000
Maintenance	59	52,600	17,300
Machining	76	120,000	45,000	61,000	140,800
Assembly	114	160,000	15,000	235,000	35,200
	310	358,900	104,200	296,000	176,000

Machining and Assembly are operating departments; the other departments are service departments. Factory Administration is allocated on the basis of labor-hours; Custodial Services on the basis of square feet occupied; Personnel on the basis of number of employees; and Maintenance on the basis of machine-hours. Required: 1. Allocate service department costs to consuming departments by the step-down method. Then compute predetermined overhead rates in the operating departments using a machine-hours basis in Machining and a direct labor-hours basis in Assembly. (Please enter allocations from a department as negative and allocations to a department as positive. The line should add across to zero. Do not round intermediate calculations. Round "Predetermined overhead rates" to 2 decimal places and other answers to the nearest whole dollar amount.) 2. Allocate service department costs to consuming departments by the direct method. Again, compute predetermined overhead rates in Machining and Assembly. (Please enter allocations from a department as negative and allocations to a department as positive. The line should add across to zero. Do not round intermediate calculations. Round "Predetermined overhead rates" to 2 decimal places and other answers to the nearest whole dollar amount.) 3. Assume that the company doesnt bother with allocating service department costs but simply computes a single plantwide overhead rate based on total overhead costs (both service department and operating department costs) divided by total direct labor-hours. Compute the plantwide overhead rate. (Round your answer to 2 decimal places.) 4. Suppose a job requires machine and labor time as follows: Machine-Hours Direct Labor-Hours Machining Department 300 27 Assembly Department 10 80 Total hours 310 107 Compute the amount of overhead cost that would be assigned to the job if the overhead rates were developed using the stepdown method, the direct method, and the plantwide method. (Round intermediate calculations to 2 decimal places and final calculations to the nearest whole dollar.)
