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?

The book was 12 days late.

Step-by-step 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 =

  = 12

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

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
