To calculate the marginal product of labor (MPL) associated with hiring a third worker, we need to determine the change in output when the third worker is hired.
- Output with 2 workers: 48,000
- Output with 3 workers: 52,000
Now, calculate the marginal product of the third worker:
\[ MPL = \text{Output with 3 workers} - \text{Output with 2 workers} \] \[ MPL = 52,000 - 48,000 = 4,000 \]
Therefore, the marginal product of labor associated with hiring a third worker is 4,000.
