here (millions of dollars): Sales for 2019 were $250 million and net income for the year was $7.5 million, so the firm's profit margin was 3.0%. Upton paid dividends of $3 million to common stockholders, so its payout ratio was 40%. Its tax rate was 25%, and it operated at full capacity. Assume that all assets/sales ratios, (spontaneous liabilities)/sales ratios, the profit margin, and the payout ratio remain constant in 2020. Do not round intermediate calculations. a. If sales are projected to increase by $40 million, or 16%, during 2020 , use the AFN equation to determine Upton's projected external capital requirements. Enter your answers in millions. For example, an answer of $10,550,000 should be entered as 10.55 . Round your answer to two decimal places. $ million b. Using the AFN equation, determine Upton's self-supporting growth rate. That is, what is the maximum growth rate the firm can achieve without having to employ nonspontaneous external funds? Round your answer to two decimal places
