Answer:
The the stock price for each company is: 
Red = $150 per share
Yellow = $60 per share
Blue = $37.50 per share 
Step-by-step explanation:
as per the devidend growth model, the share price can be given by:
Po = D1/(ke-g)
Po is the share price today
ke is the required rate of return
g is the growth rate on devidend
Red = $3/(0.08 - 0.06)
 = $150 per share
Yellow = $3/(0.11 - 0.06)
 = $60 per share
Blue = $3/(0.14 - 0.06) 
 = $37.50 per share
Therefore, The the stock price for each company is: 
Red = $150 per share
Yellow = $60 per share
Blue = $37.50 per share
