Answer:
Marginal product- 118 units
Step-by-step explanation:
The marginal product is the increase in total product as result of employing additional unit of a resource.
It is extra units of product achieved resulting from additional unit of a production resource
Marginal product = Change in total product/change in total unit of resource
= (328-210) units/(4-3) workers
= 118 units
Therefore, the last worker employed produced= 118 additional units
