Use the table to answer the question.

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?

Answer 1

To find the initial value, we need to determine how much the fine is for 1 day overdue.

To do this, we can look at the pattern in the table:
1 day = 30 cents
2 days = 30 cents + 15 cents = 45 cents
3 days = 45 cents + 15 cents = 60 cents

Since each additional day adds 15 cents to the fine, we can infer that the initial fine for 1 day overdue is 30 cents.

Therefore, the initial value is 30 cents.
