Answer: 100 bottles per labor hour
Step-by-step explanation:
To solve this question, we need to first calculate the number of labor hours used. This will be:
= 35 + 35 + 70
= 140 labor hours
Since the total number of bottles produced by the factory is 14000 bottles, then the productivity of labor will be equal to:
= Total production / Total labor hours .
= 14000 / 140
= 100 bottles per labor hour
