Use the table to answer the question.
Days | Fine
2 | 30 cents
3 | 45 cents
4 | 60 cents
The table shows the fine owed for an overdue library book according to how many days it is overdue. What is the initial value?
The initial value would be the fine for 1 day overdue.
Looking at the table, we can see that for 2 days overdue, the fine is 30 cents. This means that the additional fine for being overdue for 1 day is 30 - 0 = 30 cents.
Therefore, the initial value is 30 cents.
