Answer:
$12,000
Step-by-step explanation:
total preferred dividends per year = 1,200 x $50 x 5% = $3,000
since they were not paid during the past three years, and they are cumulative, the total preferred dividends = $3,000 x 4 = $12,000
common stock dividends = total dividends - accumulated preferred dividends = $25,000 - $12,000 = $13,000
cumulative preferred stocks that are not paid in the past, must be paid before any common dividends are paid
