Answer:
When a firm employs 1 unit of labor, it produces 8 units of output. This is because the marginal product of labor, which is the additional output produced by each additional unit of labor, is 8. so, the correct answer is 3) 8 units.
Step-by-step explanation:
The statement doesn't provide specific information about the production function or technology used by the firm. However, if we assume a certain level of productivity and efficiency, we can make an estimation based on the provided options.
Option 3) 8 units seems to be a reasonable choice, representing a level of output that is neither too conservative nor too aggressive. Keep in mind that the actual output would depend on various factors, including the technology, resources, and efficiency of the firm's production process.
Therefore, the correct answer is 3) 8 units.
