At the beginning of a given trading day, in your investment account, you had 300 shares of XYZ stock with the opening market price of $75.00 a share in assets. You also had account equity of $12,000 at the beginning of that day and the remaining amount was margin loan.

Your broker requires initial margin of 0.60, and maintenance margin of 0.40.

At the end of the trading day, you received a margin call, and you took care of that margin call by depositing additional $2,500 in your investment account.

What was the closing market price of stock at the end of the day?

Once you take care of a margin call, then your margin balance is equal to the initial margin.

Ignore the dividend income, interest amount on the initial margin deposit, and the time value of money for this problem.
