PLEASE HELP (not sure if the drop down choices are correct, either)

Payne Products had $2.4 million in sales revenues in the most recent year and expects sales growth to be 25% this year. Payne would like to determine the effect of various current assets policies on its financial performance. Payne has $2 million of fixed assets and intends to keep its debt ratio at its historical level of 45%. Payne's debt interest rate is currently 10%. You are to evaluate three different current asset policies: (1) a restricted policy in which current assets are 45% of projected sales, (2) a moderate policy with 50% of sales tied up in current assets, and (3) a relaxed policy requiring current assets of 60% of sales. Earnings before interest and taxes are expected to be 13% of sales. Payne's tax rate is 25% a. What is the expected return on equity under each current asset level? Do not round intermediate calculations. Round your answers to two decimal places. % % Restricted policy: Moderate policy: Relaxed policy: b. In this problem, we have assumed that the level of expected sales is independent of current asset policy. Is this a valid assumption? I. Yes, this is a valid assumption. The current asset policies followed by the firm mainly influence the level of long-term debt used by the firm. II. Yes, this is a valid assumption. The current asset policies followed by the firm mainly influence the level of fixed assets. III. Yes, this assumption would probably be valid in a real world situation. A firm's current asset policies have no significant effect on sales. IV. Yes, this is a valid assumption. Sales are controlled only by the degree of marketing effort the firm uses, irrespective of the current asset policies it employs. V. No, this assumption would probably not be valid in a real world situation. A firm's current asset policies may have a significant effect on sales. IV c. How would the overall risk of the firm vary under each policy? The restricted policy leads to a higher expected return as compared to moderate & relaxed policies. Lower current assets in a restricted policy would imply lower liquid assets; thus, the firm's ability to handle contingencies would be impaired. Higher risk of inadequate liquidity would increase the firm's risk of insolvency and thus increase its chance of failing to meet fixed charges. Conversely, a relaxed policy means higher liquid assets and lower total assets turnover ratio. In the relaxed policy, higher liquidity would decrease the firm's risk. The moderate policy falls between the two extremes
