Assume you buy $100$ shares of stock at $$40$ per share on margin $(40$ percent$).$ If

the price rises to $$55$ per share, what is your percentage gain on the initial equity?

In problem $1,$ what would the percentage loss on the initial equity be if the

price had decreased to $$28?$

$-3.$ Assume you have a $25$ percent minimum margin standard in problems $1$ and $2.$

With a price decline to $$28,$ will you be called upon to put up more margin to meet

the $25$ percent rule? Disregard the $$2,000$ minimum margin balance requirement.
