The firm also has a profit margin of 25 percent, a retention ratio of 20 percent, and expects sales of $7.8 million next year. Assets Liabilities and Equity Current assets $ 1,864,000 Current liabilities $ 2,265,760 Fixed assets 4,800,000 Long-term debt 1,600,000 Equity 2,798,240 Total assets $ 6,664,000 Total liabilities and equity $ 6,664,000 If all assets and current liabilities are expected to grow with sales, what amount of additional funds will Wind Em need from external sources to fund the expected growth? 640,000 seems not to be the answer
