Final answer:
The common stockholders of M. Sunland Corporation will receive $340,000 in dividends.
Step-by-step explanation:
The preferred stockholders of M. Sunland Corporation will receive dividends before the common stockholders.
Cumulative preferred stockholders have the right to receive any missed dividends in the future, in addition to the current year's dividends.
In this case, the preferred stockholders will receive $160,000 ($100 par value * 0.08 dividend rate * 20,000 shares) in dividends for 2020.
The remaining amount of $340,000 ($500,000 - $160,000) will then be distributed to the common stockholders.
