Gnomes R Us is considering a new project. The company has a debt$-$equity ratio of $\mathrm{.}75.$ The company$$s cost of equity is $14\mathrm{.}9$ percent, and the aftertax cost of debt is $8\mathrm{.}2$ percent. The firm feels that the project is riskier than the company as a whole and that it should use an adjustment factor of $+2$ percent.

What is the company$$s WACC?

Note: Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.$

What discount rate should the firm use for the project?
