Final answer:
The marginal cost of producing an additional unit of nuts for Victor is calculated by subtracting the total cost of producing one unit from the total cost of producing two units. In this case, the marginal cost is $300, which is the difference between $1800 and $1500.
Step-by-step explanation:
Victor's marginal cost of producing an additional unit of nuts is calculated based on the change in total cost associated with the change in quantity produced. As given in the background information, when output increases from 1 to 2 units, the total cost rises from $1500 to $1800. Therefore, to find the marginal cost of producing the second unit, we subtract the total cost for 1 unit from the total cost for 2 units.
Marginal cost = Total cost for 2 units - Total cost for 1 unit
= $1800 - $1500
= $300
So, the marginal cost of producing the second unit of nuts is $300.
