Qualcomm is looking to invest in a project. In order to do this, they require capital and they are concerned about how much it will cost to raise this capital. Currently, the company has $16\mathrm{.}24$ million Class A shares and $80\mathrm{.}13$ million Class B shares, they are priced at $$60\mathrm{.}02$ and $$52\mathrm{.}18$ per share respectively. The company also has $3$ types of bonds still outstanding a bond with a YTM of $3\mathrm{.}00\%$ at a market value of $$1003\mathrm{.}18$ million, another with a YTM of $4\mathrm{.}85\%$ with a market value of $$2016\mathrm{.}26$ million, and finally a third with a YTM of $10\mathrm{.}00\%$ with a market value of $$1921\mathrm{.}36$ million. The risk free rate of the market is $3\mathrm{.}15\%,$ and the market risk premium is $2\mathrm{.}36\%.$ The beta of Qualcomm is $\mathrm{.}98$ and the tax rate is $36\mathrm{.}10\%.$ What is the company's cost of capital?

Part B: the three projects are expansion projects that require varying investment totals. The first project costs $$435000\mathrm{.}00$ and would generate a yearly profit of $$76000\mathrm{.}00$ and will last for $9\mathrm{.}00$ years. The second project costs $$498000\mathrm{.}00$ but will generate a yearly profit of $$84000\mathrm{.}00$ and will last for $11\mathrm{.}00$ years. Finally, the third project will cost $$598000\mathrm{.}00,$ generate a yearly profit of $$89000\mathrm{.}00$ and will last for $16\mathrm{.}00$ years. The CFO wants your help in determining which project to choose.
