Question

Wilmington Company has two manufacturing departments--Assembly and Fabrication. It considers all of its manufacturing overhead costs to be fixed costs. The first set of data that is shown below is based on estimates from the beginning of the year. The second set of data relates to one particular job completed during the year--Job Bravo.
Estimated Data Assembly Fabrication Total
Manufacturing overhead costs $ 7,250,000 $ 7,830,000 $ 15,080,000
Direct labor-hours 145,000 87,000 232,000
Machine-hours 58,000 290,000 348,000
Job Bravo Assembly Fabrication Total
Direct labor-hours 30 22 52
Machine-hours 22 25 47
Required:
1. If Wilmington used a plantwide predetermined overhead rate based on direct labor-hours, how much manufacturing overhead would be applied to Job Bravo?
2. If Wilmington uses departmental predetermined overhead rates with direct labor-hours as the allocation base in Assembly and machine-hours as the allocation base in Fabrication, how much manufacturing overhead would be applied to Job Bravo? (Round your intermediate calculation to 2 decimal places.)
1. Plantwide manufacturing overhead applied to Job Bravo
2. Manufacturing overhead applied from Assembly to Job Bravo
Manufacturing overhead applied from Fabrication to Job Bravo
Total departmental manufacturing overhead applied to Job Bravo

Answer 1

Answer:

1. $3,380

2. $2,175

Explanation:

Part 1

Predetermined overhead rate = Total Overheads for the Company ÷ Total  Direct labor-hours for the Company

                                                  =  $ 15,080,000 ÷ 232,000

                                                  = $65

Overheads applied to Job Bravo = ( 30 x $65) + (22 x $65) =  $3,380

Part 2

Assembly department

Predetermined overhead rate =  $ 7,250,000 ÷ 145,000

                                                  = $50

Assembly department

Predetermined overhead rate =  $ 7,830,000 ÷ 290,000

                                                  = $27

Overheads applied to Job Bravo = (30 x $50) + (25 x $27) = $2,175
