Question

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?

Answer 1

$1.08/$0.09= amount of days late
answer=12 days

Answer 2

The book was 12 days late.

Explanation:

Trevor paid a total of $1.08 as a fine for an overdue library book.

Per day penalty of the book is $0.09

Let Trevor is x days late.

Then the overdue amount as a penalty will be = $0.09x

And the expression representing the overdue amount will be

0.09x = 1.08

x =
`(1.08)/(0.09)`

= 12

Therefore, Trevor was 12 days late to return the book.
