the table shows the fine owed for an overdue library book according to how many days it is overdue whats the initial value? days: (2 days: fine 30 cents ) (3 days: 45 cents) (4 days : 60 cents)

The initial fine for an overdue library book is not provided in the table. However, based on the information given, we can calculate the initial fine by finding the difference in fines for each additional day overdue.

To find the initial fine, we can start by looking at the fine for the first day overdue. Since it is not provided in the table, we can make an assumption based on the pattern in the table.

From the information given, we can see that the fine increases by 15 cents for each additional day overdue. So, if we assume that the initial fine for being 1 day overdue is 15 cents, then the fines for being 2, 3, and 4 days overdue would be as follows:

- 2 days overdue: $0.15 (initial fine) + $0.15 = $0.30
- 3 days overdue: $0.15 + $0.15 + $0.15 = $0.45
- 4 days overdue: $0.15 + $0.15 + $0.15 + $0.15 = $0.60

Therefore, based on the available information and assuming an initial fine of 15 cents for being 1 day overdue, the fines for 2, 3, and 4 days overdue would be $0.30, $0.45, and $0.60 respectively.
