Harnett Corporation has two manufacturing departments--Molding and Assembly. The company used the following data at the beginning of the period to calculate predetermined overhead rates:

Molding Assembly Total
Estimated total machine-hours (MHs) 3,000 7,000 10,000
Estimated total fixed manufacturing overhead cost $24,000 $53,200 $77,200
Estimated variable manufacturing overhead cost per MH $1.00 $2.00

During the period, the company started and completed two jobs--Job E and Job M. Data concerning those two jobs follow:

Job E Job M
Direct materials $21,600 $9,300
Direct labor cost $22,600 $9,500
Molding machine-hours 2,500 500
Assembly machine-hours 2,500 4,500

Required:
a. Assume that the company uses a plant-wide predetermined manufacturing overhead rate based on machine-hours. Calculate that overhead rate, (Round your answer to 2 decimal places.)
b. Assume that the company uses a plant-wide predetermined manufacturing overhead rate based on machine-hours. Calculate the amount of manufacturing overhead applied to Job E. (Do not round intermediate calculations.)
c. Assume that the company uses a plant-wide predetermined manufacturing overhead rate based on machine-hours. Calculate the total manufacturing cost assigned to Job E. (Do not round intermediate calculations.)
d. Assume that the company uses a plant-wide predetermined manufacturing overhead rate based on machine-hours and uses a markup of 20% on manufacturing cost to establish se ling prices. Calculate the selling price for Job E. (Do not round intermediate
calculations.)
e. Assume that the company uses departmental predetermined overhead rates with machine-hours as the allocation base in both departments. What is the departmental predetermined overhead rate in the Molding department? (Round your answer to 2 decimal places.)
f. Assume that the company uses departmental predetermined overhead rates with machine-hours as the a location base in both production departments. What is the departmental predetermined overhead rate in the Assembly department? (Round your answer to

Answer:

Results are below.

Explanation:

a) To calculate the predetermined manufacturing overhead rate we need to use the following formula:

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= (77,200 + 3,000 + 14,000) / 10,000

Predetermined manufacturing overhead rate= $9.42 per machine hour

b) To allocate overhead, we need to use the following formula:

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

Job E:

Allocated MOH= 5,000*9.42

Allocated MOH= $23,550

c) Total cost= 21,600 + 22,600 + 47,100

Total cost= $91,300

d) Selling price= 91,300*1.2= $109,560

e) Predetermined manufacturing overhead rate= (24,000/3,000) + 1

Predetermined manufacturing overhead rate= $9 per machine hour

f) Predetermined manufacturing overhead rate= (53,200/7,000) + 2

Predetermined manufacturing overhead rate= $9.6 per machine hour
