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 of being overdue.

From the table:
2 days = 30 cents
3 days = 45 cents

To find the difference between 3 days and 2 days, subtract 30 cents from 45 cents:
45 cents - 30 cents = 15 cents

Therefore, the initial value is 15 cents for 1 day of being overdue.
