Can you please check this work to see if i done it correctly. i left out section D on purpose. Thank you

Problem 9.37 Supernormal Growth Ceebros Builders is expanding very fast and is expected to grow at a rate of 25 percent for the next four years. The company recently paid a dividend of $3.60 but is not expected to pay any dividends for the next 3 years. In year 4, management expects to pay a $5 dividend and thereafter to increase the dividend at a constant rate of 6 percent. The required rate of return on such stocks is 20 percent.

a. Calculate the present value of the dividends during the fast growth period. D₀ = $3.60 g_1-4 = 25.00% Required Rate of Return (R) = 20.00% D₁ = $4.5000 PV_D₁ = $3.7500

D₂ = $5.6250 PV_D₂ = $3.9063

D₃ = $7.0313 PV_D₃ = $4.0690

D₄ = $8.7891 PV_D₄ = $4.2386

PV of Dividends (years 1-4): $15.9638

b. What is the value of the stock at the end of the fast growth period (i.e. P₄)?

Hint: Calculate D₅ (expected dividend in year 5) and use the constant growth dividend model to estimate P₄.

Constant Growth Rate (g) = 6.00%

D₅ = $9.3164

P₄ = $66.5458

c. What is the value of the stock today?

Hint: Find the present value of P₄ and add this amount to the present value of the first four years of dividends.

PV_P₄ = $26.7432

Current Price of the Stock (P₀) = $42.71

d. Would today's stock value be affected by the length of time you intend to hold the stock?
