2) Stock in Daenerys Industries has a beta of 1.14. The market risk premium is 8.5 percent, and Tbills are currently yielding 4.5 percent. The company's most recent dividend was $1.7 per share, and dividends are expected to grow at a 7 percent annual rate indefinitely. If the stock sells for $35 per share, what is your best estimate of the company's cost of equity?

Question 1:
Given :
WACC = 13%
Cost of Equity (Ke) = 18%
Pretax cost of Debt (Kd) = 7.5%
Tax Rate = 31%
Therefore,
WACC = Weight of Equity * (Ke) + Weight of Debt * (Kd) * (1tax rate)
Let the weight of Equity be 'x'; then weight of debt b '1x' :
13 = (x*18) + [(1x)*{7.5*(10.31)}]
13 = 18x + [(1x)*5.175]
13 = 18x + 5.1755.175x
135.175 = 12.825x
It implies,
12.825x = 7.825
x = 7.825/12.825
x = 0.61
Question 2:
Note : According to the data given in the question we can find out the cost of equity by two methods
1) CAPM Model
2) Dividend Discount Model
A. Calculation of Cost of Equity using CAPM :
Given :
Beta of the stocks in the industry = 1.14
Market risk premium (RmRf) = 8.5%
Tbills yield i.e., risk free rate (Rf) = 4.5%
Cost of Equity (Ke) = Rf + Beta * (RmRf)
Ke = 4.5 + 1.14 * (8.5)
Ke = 14.19%
B. Calculation of Cost of Equity (Ke) using Dividend Discount Model :
GIven :
Dividend (D0) = $1.7
Growth rate (g) = 7% or 0.07
Current Stock Price (P0) = $35
35 = [1.7*(1+0.07)]/Ke0.07
35 * (Ke0.07) = 1.819
35Ke  2.45 = 1.819
Ke = (1.819+2.45)/35
Ke = 0.12197 i.e., 12.2%
