• After you prepared the statement of comprehensive income and the supporting schedule of cost of goods manufactured for the year ended December 31, 2022.

1. How would the answer to the preceding problem be modified if you were asked for a schedule of cost of goods manufactured and sold instead of a schedule of cost of goods manufactured? Be specific.
2. Would the sales managers salary (included in marketing, distribution, and customers services cost) be accounted for differently if the Powell Corporation were a merchandising company instead of manufacturing company.
3. Plant supervisory salaries are usually regarded as indirect manufacturing costs? Give an example.
4. Suppose that both the direct materials used and plant depreciation were related to the manufacture of 1 million units of products. What is the unit cost for the direct materials assigned to those units? What is the unit cost for plant building and equipment depreciation? Assume that yearly plant depreciation is computed on a straight-line basis.
5. Assume that the historical, actual cost-behavior patterns in requirement 4 persist-that is, direct materials costs behave as a variable cost and depreciation behaves as a fixed cost. Repeat the computation in requirement 4, assuming that the costs are being predicted for the manufacture of 1.2 million units of product. How would the total costs be affected?
6. As management accountant, explain concisely to the president why the unit costs differed in requirement 4 and 5.
