Table: (2,30), (3,45), (4,60).

The Table shows the fine owed for an overdue library book based on how many days overdue it is. What is the initial value?

The initial value is the value of the table when the number of days overdue is 0.

From the given table, we can see that when the number of days overdue is 0, the fine owed is not provided. However, we can assume that when there are no days overdue, there is no fine owed.

Therefore, the initial value in this case can be assumed to be $0.
