answer below three questions, and please show calculation step

1.Firm D is an unlisted private firm. Hence, there are no stock return data to estimate the equity beta of the firm D. The firm D has the debt to equity (D/E) ratio of 0.7. The firm D's tax rate is 35%. And the average industry tax rate (t) is 35% Assume there are only three other firms (A, B and C) in the industry as shown below in the table. The table shows equity betas of the firms with the debt to equity ratios. The firm D wants to use the information available from its industry to determine its equity beta. Find out the firm D's equity beta. (Hint: use unlever and re-lever procedures) Company Equity D/E beta A 1.5 1.2 B 1.4 1.1 C 0.9 0.7 A. greater than 1.5 B. greater than 1.06 but less than 1.15 C. less than 1.0 2. Grott and Perrin, Inc., has expected earnings of $3 per share for next year. The firm's ROE is 20%, and its earnings retention ratio is 70%. If the firm's market capitalization rate is 15%, what is the present value of its growth opportunities? A. 90 B. 70 C . 50 3. By regression analysis using stock return data, the raw beta is estimated to be 1.4. The debt to equity (D/E) ratio has been 0.6. However, the firm will change the D/E to the target 0.9. What would be the equity beta (levered beta) under the target D/E ratio? Tax rate is 35%. A. greater than 1.65 B. greater than 1.55 but less than 1.65 c. greater than 1.4 but less than 1.55
