1. Your task is to write a discussion post where you choose a topic related to managerial accounting covered in class, such as cost classification, cost behavior, budgeting, or performance analysis, and relate it to a real-life company, organization, or personal experience. You may pick any topics from one or more of the chapters (Chapters 1, 2, 3, 5, 7, 8, 9, 10 and 13) we covered in class. Your post should be at least three paragraphs long for this task (see my sample in the discussion board). [30 points towards Exam 3]
