Answer:
Re = 8.79%
Explanation:
annual growth rates:
($1.38 - $1.25) / $1.25 = 0.104
($1.49 - $1.38) / $1.38 = 0.078
($1.60 - $1.49) / $1.49 = 0.074
($1.69 - $1.60) / $1.60 = 0.056
geometric growth rate = ⁴√(1.104 x 1.078 x 1.074 x 1.056) - 1 = ⁴√1.34976 - 1 = 1.0779 - 1 = 0.0779 = 7.79%
P₀ = Div₁ / (Re - g)
$199 = $2 / (Re - 0.0779)
Re - 0.0779 = $2 / $199 = 0.01
Re = 0.01 + 0.0779 = 0.0879 = 8.79%
