The late fee for library books is $2.00 plus 15¢ each day for a book that is late. if maria’s fee for a late book was $3.20, write and solve a linear equation to find how many days late the book was.

Which number line represents the solution set for the inequality - x 24?

Is the point (0, 8) on the x-axis or y-axis? how do you know?
