Answer:
Results are below.
Explanation:
<u>To calculate the predetermined manufacturing overhead rate we need to use the following formula:</u>
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= (3,760,000 / 235,000) + 2
Predetermined manufacturing overhead rate= $18 per machine hour
Job P90:
Direct materials $ 1,794
Direct labor cost $ 1,287
Machine-hours used 86
<u>We need to allocate overhead costs:</u>
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 18*86= $1,548
Total manufacturing costs= 1,548 + 1,794 + 1,287
Total manufacturing costs= $4,629
