Answer:
9
Step-by-step explanation:
From the given information:
The formula for calculating the average product AP =
![(Total \ Product )/(Labor)](https://img.qammunity.org/2021/formulas/business/college/47sq8vjg3n3rhdfeqsfc28s7gyq6a8hgv5.png)
When the input of labor = 2
The total product = 18
∴
The average product (AP) for two inputs of labor =
![(18)/(2)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/vvtmh3p2jdx29bzp2lasoe0x9ddrpe7clh.png)
The average product (AP) for two inputs of labor = 9
