# Thread: Story problem with absolute values

1. ## Story problem with absolute values

In a wood shop, you must cut several pieces of wood to within 5/16 inch of specification. If the specification is 3 1/8 inches, then what lengths are acceptable for your cut pieces? A hint he gives me is, you can set this up directly as an absolute value inequality and solve that, or you can set it up as a compound linear inequality and solve that, you mihght be able to do it in your head but show what you did. Thanks for the help in advance guys, you ROCK!

2. or he says you can use a number line, please help, i can't figure this out for the life of me!
