Answer:
a. 7.03%
Explanation:
We need to solve for the rate of sustainable growth which is the amount of growth without chanign the capital structure of the company
ROE ( 1 - dividend payout) = sustainable growth
ROE income / equity = 1,420,00 / 11,115,000 = 0.127755285
0.127755285 ( 1 - 0.45) = 0.0702654 = 7.03%
