Answer:
total dividends distributed to common stock $6,000
dividends per common stock $0.12
Explanation:
preferred stock dividends = 1,000 x 6% x $50 = $3,000
since they are cumulative, if the dividends are not paid during one year, they must be paid in the next periods
the distribution of the $10,000 in dividends in 2018:
dividends per common stock = $6,000 / 50,000 = $0.12
