Assume the following data: EBIT = 400; Net income = 100; Equity = 1,000. Calculate the ROE (return on equity). Assume the following data: EBIT = 400; Tax = 100; Sales = 3,000; Total assets = 1,500. Calculate the ROA (return on assets). 13) Assume the following data: EBIT = 400; Tax = 100; Sales = 3,000; Average total assets 1,500. Calculate the profit margin. 14) Assume the following data: Sales = 3,200; Cost of goods sold = 1,600; A/R (Account Receivables) = 200. Calculate how many days it takes to collect cash from A/R (i.e., convert A/R into cash). 15) Assume the following data: Sales = 3,200; Cost of goods sold = 1,600; Total assets = 1,600; Inventory = 200. Calculate how many days it takes to turn over inventory (ie, sell the inventory). 16) Assume the following data: Sales = 3,200; Cost of goods sold = 1,600; Total assets = 1,600; Inventory = 200. Calculate the asset turnover ratio. 17) Assume the following data: Current assets = 500; Current liabilities=250; Inventory = 200; Accounts receivable = 200. Calculate the cash ratio. (Assume that the firm has no marketable securities.) 18) Assume the following data: Current assets = 500; Current liabilities=250; Inventory = 200; Account receivables = 200. Calculate the quick ratio. 19) Assume the following data: Long-term debt = 100; Value of leases = 20; Book value of equity = 80. Calculate the debt-equity ratio. 19) 20) Assume the following data: Long-term debt = 100; Value of leases = 20; Book value of equity = 80. Calculate the debt ratio. 21) If the debt ratio is 0.5, what is the debt-equity ratio? (Assume no leases.) 20) E
