KT Enterprises is considering undertaking a new project. Based upon analysis of firms with similar projects, KT has determined that an unlevered cost of equity of $11\%$ is suitable for their project. KT$\text{'}$s corporate tax rate is $21\%,$ its borrowing rate is $6\%,$ and KT does not believe that its borrowing rate will change if the new project is accepted.

If KT expects to maintain a debt to equity ratio for this project of $0\mathrm{.}7$ then KT$\text{'}$s project$-$based WACC, rwacc, for this project is closest to $(2$ decimal places$)$: the answer is $10\mathrm{.}48$ I just do not know how to get it
