Answer:
11.7%
Explanation:
The common stock of a shaky building has a beta of 22%
The market risk premium is 9.56%
The US treasury bill is 3.3 %
Therefore the cost of equity can be calculated as follows
= 3.3/100 + (1+22/100)(9.56)
= 0.033 + (1+0.22)(9.56)
= 0.033 + 1.22×9.56
= 0.033 + 11.6632
= 11.7%
