7.(Chapter 13) Bay Corp. has a debt-equity ratio of 0.25 (1/4). The company is considering a new plant that will cost $800 million to build. When the company issues new equity, it incurs a flotation cost of 9 percent. The flotation cost on new debt is 2 percent. a. What is the initial cost of the plant if the company raises all equity externally (and funds the project with the company's debt-equity ratio)? Note: The debt and equity ratios, (B/V) and (S/V), can be calculated as follows: With (B/S)-0.25, (S/S)+(B/S) (V/S) 125. Therefore (S/V)-1/1.25-8 and (B/V)-1-(S/V)-2 b. What is the initial cost of the plant if the company raises 50 percent of the new equity required using retained earnings (and funds the project with the company's debt-equity ratio)
