Given data:
Initial margin given is 50, amount of investment 3000, price of the stock = $60 .
In order to calculate the number of shares, the following formula will be used by the company
5 = [(Q multiply with $60) minus $3,000] divide by (Q multiply with $60);
$30Q = $60Q minus $3,000; $30Q = $3,000;
Q = 100.
