The risk-free rate is 5%, the return on the stock market is 12.5% and the firm has a beta of 1.75.The last dividend paid was $1.00 and its growth rate expected in earnings and dividends is 6 percent. The firm plans to finance all capital expenditures with 40 percent debt and 60 percent equity with a stock price is $8.75.

Can you help me solve for the average cost of equity using two methods: 1) CAPM & 2) the discounted dividend approach?

Also, can you please help me figure out the firms overall weighted average cost of capital (WACC)?
