Answer:
17 units per hour or 85 units per labor
Explanation:
The per hour productivity of a single labor for non-defective units is 17.
You can come to this conclusion using following mathematical calculation
STEPS:
1. 500 units (15% defective)
500-(15% of 500)=425 units
2. 5 workers working a 5 hour shift, 425 units divided by 5 hours
425/5= 85 units per hour
3. 85 units are produced in an hour divided by 5 workers
85/5= 17 units per worker
Thus 17 non-defective units are produced by a single worker in an hour.
