Question: 

Scenario: Wilson Corporation (not real) has a targeted capital structure of 40% long term debt and 60% common stock. The debt is yielding 6% and the corporate tax rate is 35%. The common stock is trading at $50 per share and next year's dividend is $2.50 per share that is growing by 4% per year.

• Calculate the company's weighted average cost of capital. Use the dividend discount model. Clearly show calculations..
• The company's CEO has stated if the company increases the amount of long term debt so the capital structure will be 60% debt and 40% equity, this will lower its WACC. I need help explaining why i should agree or disagree and then i need help defending why i agree or disagree.
• How should i advise the CEO?

Please give through explanations and show/explain your answers and suggestions.
