Cost of new common equity is found by using Dividend (D0), growth rate (g) and Price of the newly issued stock (P0).
where, D0 = $2 per share
P0 = $34
g = 10%
Cost of new common equity = {D0*(1+g)}/P0 + g
Cost of new common equity = [$2*(1+0.1)]/34 + 0.1
= (2.2)/34 + 0.1
= 16.47% or 16.5%
Therefore the correct answer is 16.50% (b)
