Can you please explain to me how the program got the result of 28.95?

I got how the 1.05 is calculates . Is it 20/19?

The correct answer is shown. A rights offering conveys the right to purchase 2 shares for every 17 shares held at $20 per share. The stock is currently trading at $30 per share. The average price of the share is theoretically 28.95 and the value of the right is theoretically 1.05 (round to the nearest cent). Your answer is correct. Read about this Challenge OK
