Answer:
1. Form A$80 per machine hour
Form B $4 per direct labor hour
2.Form A from $3.84 to $10.00
Form B from $7.30 to $3.60
3. Form A Unit overhead cost $ 3.87
Form B Unit overhead cost $ 7.28
Explanation:
Lansing, Inc
1. Overhead rates for each department will be;
Molding
$400,000/5,000
= $80 per machine hour
Polishing
$80,000/20,000
= $4 per direct labor hour
2. The overhead assignment:
Form A
($80 ×3,500) + ($4 ×5,000)
$280,000+$20,000
=$300,000
Form B
($80 ×1,500) + ($4 ×15,000)
$120,000+$20,000
=$180,000
Total applied overhead $300,000 and $180,000
Units of production Form A :
300,000÷30,000
=Unit overhead cost $10.00
Units of production Form B
180,000÷50,000
= Unit overhead cost $3.60
Plantwide rate Will be :
$480,000/25,000
= $19.20 per direct labor hour
Form A overhead cost in units will be:
$19.20 ×6,000/30,000
$19.20×0.2
$3.84
Form B overhead cost in unit will be :
$19.20 ×19,000/50,000
$19.20×0.38
$7.296 approximately $7.30
The plantwide rate for Form A
$3.84 to $10.00
The plantwide rate for Form B
$7.30 to $3.60
3. Overhead assignment:
Form A
($80 ×1,200) + ($4 ×5,000)
=$96,000+$20,000
=$116,000
Form B
($80 ×3,800) + ($4 ×15,000)
=$304,000 +$60,000
=$364,000
Total applied overhead
Form A $116,000
Form B $364,000
Units of production
Form A
$116,000 ÷ 30,000
=Unit overhead cost $ 3.87
Form B
$364,000÷ 50,000
Unit overhead cost $ 7.28
When compared to the plantwide unit overhead costs the cost will be $0.03 more higher for Form A and $0.02 less for Form B.
Which means that departmental rates may not cause a change in the assignments because It will depends on the complexity of each product and the way in which the resource demands are been made in each of the department.
