Hamada$$s equation can be used to estimate the change of beta resultant from a change in leverage. Suppose a company has a beta of $1,10$ with a debt$/$equity ratio of $2$ and that the applicable tax rate is $27\%.$ What would the unlevered beta be for the company as determined by the equation?

a$.$

$0\mathrm{.}45$

b$.$

$0\mathrm{.}41$

c$.$

$2\mathrm{.}00$

d$.$
