Suppose you have a margin account with a broker which requires the value of your equity in your account to be at least 35% of total account value. You have $50,000 to invest. You borrow $30,000 on the margin and buy shares of XYZ for $80,000 at $80 a share.

After your purchase the price of XYZ has fallen to $60 after 40 days. On the 41st day, the price rapidly declines to $39.1.

You get a margin call from your broker, but instead of depositing more cash into your account, you ask the broker to liquidate part of your holdings of XYZ to meet margin requirements. What dollar value of shares will the brokers sell?
