Answer
Table 1 - Marginal product of labor example question
Solution:
We use the marginal product of labor formula:
\(MPL=\frac{\Delta\ Q}{\Delta\ L}\)
With the addition of the second worker, we have:
\(MPL_2=\frac{20-10}{2-1}\)
\(MPL_2=10\)
With the addition of the third worker, we have:
\(MPL_3=\frac{25-20}{3-2}\)
\(MPL_3=5\)
