So really struggling on these 14 questions out of 100. I figured out the rest but am struggling a bit on thse True or false and 2 multiple choice if i can get help and feedback would be great thank you !

1. Suppose a company evaluates divisional performance using both ROI and residual income. The company's minimum required rate of return for the purposes of residual income calculations is 12%. If a division has a residual income of $6,000, then its ROI is less than 12%. t/f

2. Financial measures such as ROI are generally better than nonfinancial measures of key success drivers such as customer satisfaction as leading indicators of future financial performance. t/f

3. An advantage of using ROI to evaluate performance is that it encourages the manager to reduce the investment in operating assets as well as increase net operating income. t/f

4. Net operating income is income before interest and taxes. t/f

5. In essence, a balanced scorecard lays out a theory of how the company can take concrete actions to attain its desired outcomes. The strategy should seem plausible, but it should be regarded as only a theory. t/f

6. Residual income is the difference between net operating income and the product of average operating assets and the minimum rate of return. t/f

7. Future costs that do differ among the alternatives are not relevant in a decision. t/f

8. The book value of an old machine is always considered an opportunity cost in a decision. t/f

9. A vertically integrated company is less dependent on its suppliers than a company that is not vertically integrated. t/f

10. A disadvantage of vertical integration is that by pooling demand for parts from a number of companies, a supplier may be able to enjoy economies of scale that result in higher quality and lower cost than if every company makes its own parts. t/f

11. In a special order situation that involves using capacity that is not idle, opportunity costs are zero. t/f

12. A cost that will be incurred regardless of which alternative is selected is not relevant when choosing between the alternatives.t/f
