Solutions available for the FIFO version of the revised edition (green and white cover). 3rd edition solutions (blue cover) are now available for sale at Notes-n-Quotes. NEW THIS SEMESTER FOR BILLY'S VIDEO: This semester, the blue version contains a study guide that shows you how we got the numbers we used, finally! You can still ask questions at no extra charge, but hopefully this will help if you have different numbers than are being used in the booklet, and is very useful if you are studying for a test.
