Adidas is looking to compute its WACC. Suppose their tax rate is $27\mathrm{.}0\%,$ the market risk premium is $6\mathrm{.}4\%,$ and the$$ risk$-$free interest rate is $5\mathrm{.}4\%.$ They have an equity beta of $1\mathrm{.}28.$ The YTM of their debt is $7\mathrm{.}5\%,$ while their probability of default is $10\%.$ If they$$ default, investors expect to receive only $60$ cents per dollar owed. And Adidas wants to maintain a capital structure where $30\%$ of their capital comes from debt$($with the rest from$$ equity.$)$ What is$$ Adidas' WACC?
