RedEx Shipping determined the rate to apply overhead based on direct labor hours would be $5.40, and based on machine hours would be $4.20. Job 664 used $26.00 of direct materials, 2.5 machine hours, and 4 hours of direct labor at a cost of $14 per hour. How much is the manufacturing cost of job 664 if RedEx Shipping applies overhead based on machine hours? a. $92.50
b. $10.50
c. $21.60
d. $103.60

Manufacturing cost= $92.5

Explanation:

Giving the following information:

Predetermined overhead rate= $4.2 per machine hour

Job 664:

2.5 machine hours

$26.00 of direct materials

4 hours of direct labor for $14 per hour.

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

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

Allocated MOH= 4.2*2.5= $10.5

Now, the manufacturing cost:

Manufacturing cost= 10.5 + 26 + 4*14

Manufacturing cost= $92.5

b is the correct answer
