Milton Glasses recently paid a dividend of $1.70 per share, is currently expected to grow at a constant rate of 5%, and has a required return of 11%. Milton Glasses has been approached to buy a new company. Milton estimates if it buys the company, its constant growth rate would increase to 6.5%, but the firm would also be riskier, therefore increasing the required return of the company to 12%. Should Milton go ahead with the purchase of the new company?

How calculate that?
