B. $115.90
C. $122.90
D. $100.50

Total unitary cost= $121.5

Explanation:

Giving the following information:

Each ceiling fan has 20 separate parts.

The direct materials cost is $85

Each ceiling fan requires 3.5 hours of machine time to manufacture.

Activity Allocation Base Allocation Rate

Materials handling Number of parts $ 0.08

Machining Machine hours 7.20

Assembling Number of parts 0.35

Packaging Number of finished units 2.70

To calculate the unitary manufacturing cost, we need to use the following formula:

Unitary manufacturing cost= direct material per unit + allocated overhead per unit

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Materials handling= 0.08*20= $1.6

Machining= 7.20*3.5= $25.2

Assembling= 0.35*20= $7

Packaging= 2.70*1= $2.7

Total= $36.5

Total unitary cost= 85 + 36.5= $121.5
