A company issued 100,000 shares of common stock with a par value of $1 per share. The stock sold for $20 per share. By what amount does stockholders’ equity increase?
a. $100,000

b. $1,900,000

c. $2,000,000

d. No change in stockholders’ equity

The available chegg answers are very confusing, some accounts the $2 million (and divide it bet capital and additional paid in capital) while others say this is the increase in the SE which means (sold price - par value) * no. of shares. Please don't answer if you aren't expert, thanks
