NO.PZ2015122801000052 问题如下 BeCompany is expecteto have a payout ratio of 50% angrowth rate of 10%. Assume the rate of return is 15%, Whis the firm's leang price-to-earnings (P/E) ratio? A.9x. B.10x. C.11x. B is correct.P/E=vint payout ratio /( k-g) = 0.5 / (0.15 - 0.1) = 10x.B是正确的。本题考察的是leang P/E的计算公式应用。P/E1 = （1-b）/(k-g) = 0.5/(0.15-0.1) = 10 请问如果payout ratio是70%那b是不是就等于30%？那公式的分子就是1-30%？

NO.PZ2015122801000052 如果vinpayout ratio = 1 - RR 那么vinpayout ratio就是vin、 vinpayout ratio 怎么会等于 E vinpayout ratio直译不就是分红比例吗，一单位收益有多少是分红，多少是留存 P/E=vint payout ratio /( k-g) = 0.5 / (0.15 - 0.1) = 10x. 请问E在哪里，题目里在哪里体现？
10x. 11x. B is correct. P/E=vint payout ratio /( k-g) = 0.5 / (0.15 - 0.1) = 10x.请问可以表述一下答案公式的文字含义吗？谢谢
payout ratio=1-RR吗
