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 calculotions. Round your answer to 3 decimal places. (e.g., 32.161))
