The risk free rate of the market is $6\mathrm{.}54\%,$ and the market risk premium is $6\mathrm{.}98\%.$ The beta of Qualcomm is $1\mathrm{.}50$ 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 second project costs $$500000\mathrm{.}00$ but will generate a yearly profit of $$92000\mathrm{.}00$ and will last for $11\mathrm{.}00$ years.
