Could I get some help with the following question please!

Consider the following figures: Net Current Assets = $100 Net Fixed Assets = $200 Long Term Debt = $150 Equity = $150 Sales = $1000 Costs = $800 Taxes = $68 Assume that costs and assets increase at the same rate as sales, but debt and equity do not. The tax rate is constant. Also assume that 80% of net income is paid out in dividends, and the firm's fixed assets are being used at 90% capacity. If sales grow by 25%, what is the EFN needed
