Answer:
Margin in Dee's account when she first purchase the stock is $8,000
Step-by-step explanation:
The total value of stock purchased = $40 × 300 shares = $12,000
Since the amount borrowed from the broker is $4,000. Therefore, Dee's margin will be calculated as;
= Total purchase price - Net borrowing
= $12,000 - $4,000
= $8,000
