The Stock split changes only the number of shares and the par value per share, it does not make any change in the total par value of the common stock and the total amount of the stockholders' equity.
Hence, the total par value of the common stock shall remain same $30,000
and the total amount of the stockholders' equity shall be calculated as follows:
Stockholders' equity= Par value of Common stock + Additional Paid in Capital + Retained earnings
= 30,000+100,000+100,000
= $ 230,000
Hence, the total par value of the common stock shall be $30,000 and the total stockholders' equity shall be $ 230,000
