爱吃草莓的葡萄同学你好。题目信息：“The current price of a stock is $25 per share. You have $10,000 to invest. You borrow an additional $10,000 from your broker and invest $20,000 in the stock. If the maintenance margin is 30 percent, at what price will a margin call first occur?
A.$9.62.
B.$17.86.
C.$19.71.”
问题回复：margin=E/A，这是保证金比率的定义与计算公式。初始保证金比率等于初始自有资金比上总投资。
