2. Based on the current D/V = 0.3 and E/V = 0.7, Portland Energy Resources firm's levered Beta is 1.5. However, the cost of debt and equity ratio and the WACC formula should ideally represent long-term capital ratios, expressed on a market-value basis.

Unlever and lever Beta to reflect the long-term D/E target of 0.8, and t of 0.30.

Please provide answers and show work, thank you very much!
