Answer:
The current value of stock is $21.60 per share.
Explanation:
The current value of the stock whose dividends are growing/declining at a constant rate can be calculated using the constant growth model of DDM.
The growth will be taken as a negative percentage in case the growth rate is falling. So, g will be g= -0.1 or -10%. The formula for price under this model is,
P0 = D0 * (1+g) / ( r - g)
Where,
Taking g as -0.1.
P0 = 6 ( 1 - 0.1) / (0.15 + 0.1)
P0 = $ 21.60
