Answer:
The numbers are missing, so I looked for a similar question and found the attached images.
inventory turnover ratio = cost of goods sold / average inventory
cost of goods sold = $437,000
initial inventory = $30,000
ending inventory = $448,500 - $437,000 = $11,500
inventory turnover ratio = $437,000 / [($30,000 + $11,500)/2] = 21.06
The inventory turnover ratio shows use how fast a company sells its inventory, so the higher, the better. If the company's turnover ratio is higher than the industry's average, it means that it is more efficient at selling its inventory.
