Answer and Explanation:
The computation of the filling of the given table for the production cost is shown in the attachment below:
As we know that
Total cost = Fixed cost + variable cost
Average fixed cost = fixed cost ÷ websites
Average Variable cost = Variable cost ÷ websites
Therefore the average total cost is
= Average fixed cost + average variable cost
The marginal cost is
= Change in total cost ÷ change in quantity
These formulas are used to complete the table as given below.
