I would like you to read about activity based costing in chapter five of our textbook. Then I would like you in your post to summarize what is meant by this concept. Then I would like you to go to page 228-229 in your textbook. Read case 5-70 and answer the three questions. 1. Is the controller, Erin Jackson, acting ethically? 2. Is the production manager, Alan Tyler, acting ethically? 3. What are Jackson’s ethical obligations? To the president? To her friend? Answer should be 275 words in APa format. You must have at least one course (our text) and one non-course scholarly/peer reviewed source in your initial posting. Sources require in-text citations and must be incorporated into the body of the post in addition to a full APA citation at the end of the post.
