we'll need a million dollars in capital,As a result of our forecasting process, we determined that net income for next year will be $750. Actually 750,000. We expected our dividend will be 3%. And so we'll have 450. Leftover out of net income to add to retained earnings next year.

suppose that:

expected net income 750

less dividend payout 300

est. addition to RE 450

my question: why the dividend payout is 300?
