Trevor paid a total of $1.08 in fines for an overdue library book. If the penalty for overdue books is $0.09 per day, how many days late was the book?

Question

2 days
8 days
12 days
20 days

Answer 1

To find out how many days late the book was, we can divide the total fine by the daily penalty. The total fine is $1.08, and the penalty per day is $0.09.

We can calculate the number of days late as follows:

\[ \text{Number of days late} = \frac{\text{Total fine}}{\text{Penalty per day}} = \frac{1.08}{0.09} \]

Now, performing the division:

\[ 1.08 \div 0.09 = 12 \]

So, the book was 12 days late.
