Answer:
D) Ke = 11.79%
Step-by-step explanation:
We will use the gordon dividen grow model to sovle for the cost of new equity

we clear for return

and we consider the impact of flotation ost, because this is new equity, which reduce the proceeds from the stock

next year dividend 1.50 x 1.08 = 1.62
flotation cost 5% = 0.05
Stock 45
grow 0.08

Ke = 0.117894737 = 11.79%
