![cost \ of \ common \ stock=Risk \ free \ rate+Beta* Market \ risk \ premium](https://img.qammunity.org/2021/formulas/business/high-school/k6cyrwx0md57mcrdq7pvtcfz5n7bbutuao.png)
On substituting the estimated values, we get
⇒
![=5+(1.25* 8)](https://img.qammunity.org/2021/formulas/business/high-school/vjo6dk793k00mh39sn4y24tgzy9qfixzan.png)
⇒
![=15 \ percent](https://img.qammunity.org/2021/formulas/business/high-school/pm3cwt653o0zdv3kege7m9mz34unutrfse.png)
The total value will be:
