More on the AFN $($Additional Funds Needed$)$ equation

Green Caterpillar Garden Supplies Inc. reported sales of $$820,000$ at the end of last year, but this year, sales are expected to grow by $10\%.$ Green Caterpillar expects to maintain its current profit margin of $21\%$ and dividend payout ratio of $10\%.$ The following information was taken from Green Caterpillar$$s balance sheet:

Total assets:$$450,000$

Accounts payable:$$70,000$

Notes payable:$$45,000$

Accrued liabilities:$$60,000$

Based on the AFN equation, the firm$$s AFN for the current year is $\_\_\_\_\_\_\_\_\_.$

A positively signed AFN value represents:

a surplus of internally generated funds that can be invested in physical or financial assets or paid out as additional dividends.

a point at which the funds generated within the firm equal the demands for funds to finance the firm$$s future expected sales requirements.

a shortage of internally generated funds that must be raised outside the company to finance the company$$s forecasted future growth.

Because of its excess funds, Green Caterpillar Garden Supplies Inc. is thinking about raising its dividend payout ratio to satisfy shareholders. Green Caterpillar could pay out $\_\_\_\_\_\_\_\_$of its earnings to shareholders without needing to raise any external capital. $($Hint: What can Green Caterpillar increase its dividend payout ratio to before the AFN becomes positive?$)$
