關於維持保證金一題 - 證照

Table of Contents

題目如下
You sold short 100 shares of common stock at $45 per share. The initial margin is 50%. At what stock price would you receive a margin call if the maintenance margin is 35%?

他解答寫
Equity=100*45*1.5=6750
0.35=(6750-100p)/100p
P=50

我有點看不懂解答的意思
麻煩高手指點迷津一下
小弟先謝過了……
