Your boss, whose background is in financial planning, is concerned about the company's high weighted average cost of capital $($WACC$)$ of $26\mathrm{.}00\%.$ He has asked you to determine what combination of debt$-$equity financing would lower the company's WACC to $15\mathrm{.}00\%.$ If the cost of the company's equity capital is $6\%$ and the cost of debt financing is $28\mathrm{.}00\%,$ what debt$-$equity mix would you recommend? $($Round the final answers to three decimal places.$)$

The debt$-$equity mix should be $\%$ debt and $$ equity financing.
