Answer
Given, 
current dividend, D₀ = $3.80, g₁ = g₂ = g₃ = 15%, 
g = 5% and required return, k = 16%
Expected dividend, D₁= D₀ x (1 + g₁) 
 = $3.80 x (1.15) = $4.37
Expected dividend, D₂ = D₁ x (1 + g₂) 
 = $4.37 x (1.15) = $5.026 
Expected dividend, D₃ = D₂ x (1 + g₃) 
 = $5.026 x (1.15) = $5.779 
Expected dividend, D₄ = D₃ x (1 + g) 
 = $5.779 x (1.05) = $6.068
The price at the end of year 3, P₃ is


P₃ = $55.166
The current share price, P₀is


P₀ = $46.54
