Answer:
The answer is 5.13percent
Step-by-step explanation:
The formula to be used here is from Capital Asset Pricing Model (CAPM) and it is used to determine the cost of equity or the expected return on a company's equity.
The formula is
Ke = Rf + beta(Rm - Rf)
Where Ke is Cost of equity(13 percent)
Rf is the risk free rate of return
Rm is the market risk(9.5 percent)
beta = 1.80
To solve for Rf;
0.13 = Rf + 1.8(0.095 - Rf)
0.13 = Rf + 0.171 - 1.8Rf
0.13 - 0.171 = Rf - 1.8Rf
-0.041 = -0.8Rf
Rf = 0.041 รท 0.8
=0.0513
5.13percent
