Suppose that the financial ratios of a potential borrowing firm took the following values: X1 = Net working capital/Total assets = 0.20, X2 = Retained earnings/Total assets = 0.30, X3 = Earnings before interest and taxes/Total assets = 0.21, X4 = Market value of equity/Book value of long-term debt = 0.50, X5 = Sales/Total assets ratio = 0.8. Calculate the Altman's Z-score for this firm. (Do not round intermediate calculations. Round your answer to 3 decimal places. (e.g., 32.161)) Altman's Z-score
