Refer to Exercise 5-8. After completing Northstar's income statement for the year ended March 31, 20X2, compute these ratios to evaluate Northstar's performance: Gross profit percentage Inventory turnover (Ending inventory one year earlier. at March 31, 20X1, was $30,500.) Compare your figures with the 20X1 gross profit percentage of 48% and the inventory turnover rate of 3.16 for 20X1.
