Answer:
35.035 rate per labour hour
Step-by-step explanation:
We are asked for the traditional costing system:

The manufacturing overhead will be the sum of each activity cost:
Ordering and Receiving Orders $ 130,000
Machine Setup Setups $ 306,000
Machining Machine hours $ 1,537,500
Assembly Parts $ 1,220,000
Inspections $ 310,000
Total Overhead: $ 3,503,500
Now we divide by the cost drive which is labour hours: 100,000
3,503,500 / 100,000 = 35.035 rate per labor hour
