The marginal product of labor (MPL) is calculated by finding the change in output (meals produced) when an additional employee is hired.
Initially, the restaurant produces 250 meals with 5 employees. After hiring an additional employee, the output increases to 260 meals.
To find the marginal product of labor, use the formula:
\[ MPL = \frac{\text{Change in output}}{\text{Change in number of employees}} = \frac{260 - 250}{1} = \frac{10}{1} = 10 \]
So, the marginal product of labor is 10.
