Answer/ explanation:
Using the finite constant dividend model except with f (use infinite constant dividend model)
Price = Dividend × (1 – 1/(1+r)n) / r
a.Price = $2.25 × (1 – 1/(1.12)10/ 0.12 = $2.25 × 5.6502 = $12.71
b.Price = $2.25 × (1 – 1/(1.12)15/ 0.12 = $2.25 × 6.8109 = $15.32
c.Price = $2.25 × (1 – 1/(1.12)40/ 0.12 = $2.25 × 8.2438 = $18.54
d.Price = $2.25 × (1 – 1/(1.12)60/ 0.12 = $2.25 × 8.3240 = $18.73
e.Price = $2.25 × (1 – 1/(1.12)100/ 0.12 = $2.25 × 8.3332 = $18.75
f.Price = $2.25 / 0.12 = $18.754.
