Answer:
Results are below.
Explanation:
First, we need to calculate the predetermined overhead rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 205,000 / 41,000
Predetermined manufacturing overhead rate= $5 per direct labor hour
Now, we can calculate the profit of each service:
Residential:
Revenue= 30,000*60= 1,800,000
Direct labor costs= 30,000*16= (480,000)
Overhead= 5*30,000= (150,000)
Gross profit= $1,170,000
Commercial:
Revenue= 11,000*45= 495,000
Direct labor costs= 11,000*16= (176,000)
Overhead= 5*11,000= (55,000)
Gross profit= $264,000
