In my Fundamentals of Corporate Finance book is the following pargraph,
The TICO Corporation currently pays a cash dividend of $5 per share. You believe the dividend will be increased by 4 percent each year indefinitely. How big will the dividend be in eight years?
I don't understand why they used the simple future passive here instead of just the simple future, that is
You believe the dividend will increase by 4 percent each year.
Is there a reason for using one of the two and not the other?
Also just to make sure that my understanding is correct that saying in the simple future passive sentence "by 4 percent" it is not the subject of the sentence, the subject of this sentence is omitted. Right?
