If possible can you show the formula used or just show your work? Thanks!

The 2020 balance sheet of Osaka's Tennis Shop, Incorporated, showed $580,000 in the common stock account and $3.5 million in the additional paid-in surplus account. The 2021 balance sheet showed $620,000 and $3.9 million in the same two accounts, respectively. If the company paid out $520,000 in cash dividends during 2021 , what was the cash flow to stockholders for the year? (Enter your answer in dollars, not millions of dollars, e.g., 1,234,567.)
