Answer:
9
Explanation:
From the given information:
The formula for calculating the average product AP = [tex]\dfrac{Total \ Product }{Labor}[/tex]
When the input of labor = 2
The total product = 18
∴
The average product (AP) for two inputs of labor = [tex]\dfrac{18}{2}[/tex]
The average product (AP) for two inputs of labor = 9
