Answer:
The normal production process should be followed.
Step-by-step explanation:
The normal process should be used because when it uses the process “X” then the marginal productivity of labor (MPL) is 8 units and the wage of labor is $10 per hour. Secondly, when it uses a normal production process then the marginal productivity of labor is 10 units and the wage rate is the same that is $10 per hour. Therefore, the normal production process is giving the greater marginal productivity of labor, accordingly this process should be followed.
