Find the NPV of each project, using the firm's cost of capital. Which project is preferred in this situation?

The firm uses the following equation to determine the risk$-$adjusted discount rate, $RAD{R}_j,$ for each project $j$ :

$RAD{R}_j=R_F+{}_j(r_m-R_F)$

Where

$R_F=$ risk$-$free rate $=2\%$

$B_j=$ beta $of$ project $j$

$RAD{R}_j=$ risk$-$adjusted discount rate for project $j$

$r_m=$ expected return $on$ market portfolio $=10\%$

Substitute each project's beta into this equation to determine its RADR.

Use the RADR for each project to determine its risk$-$adjusted NPV$.$ Which project is preferable in this situation?

Compare and discuss your findings in parts a and c$.$ Which project do you recommend that the firm accept? SHOW FORMULAS IN EXCEL THANK YOU :)
