27abc = 3*3*3*a*b*c

Common factors of the above:

3*3*a*b*c= 9abc

So the answer:

Answer:

Step-by-step explanation:

present value of dividend for three years =

2.50 x 1.2 / 1.15 + 2.5 x 1.2² / 1.15² + 2.5 x 1.2³ / 1.15³

= 2.6087 + 2.722 + 2.84

= 8.17

present value of future cash flow after three years

= 2.5 x 1.2³ x 1.08 / .15 - .08

66.65

present value

= 66.65 / 1.15³ = 43.823

Total present value = 43.823 + 8.17

= 52 approx .
