$($CHAPTER $14)$

Cyber Tires would like to start a new project which will be as risky as the company's current projects. For this new project, the company plans to raise money by selling new equity, new preferred stock shares, and new debt in the following amounts: $$740,000,$$$248,000,$ and $$396,000.$ The annual costs of equity, preferred stock, and debt equal $14\%,7\%,$ and $4\%,$ respectively. Cyber Tires falls into $26\%$ corporate income tax bracket.

Calculate Cyber Tires' average annual cost of running its tire business, also known as the Weighted Average Cost of Capital.

Your answer should be in percent, not in decimals: e$.$g$.,10\mathrm{.}23$ rather than $0\mathrm{.}1023.$

Increase decimal places for any intermediate calculations, from the default $2$ to $6$ or higher, and only round your final answer to TWO decimal places: for example, $10\mathrm{.}23$

Do NOT use $"\%"$ in your answer.
