    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!
