Answer:
the information is missing, so I looked for a similar question and found the attached image:
a) days inventory on hand = (average inventory / cost of goods sold) x 365 = ($14,000 / $120,000) x 365 = 42.58 days
b) inventory turnover ratio = cost of goods sold / average inventory = $120,000 / $14,000 = 8.57
I agree with Mr. David because the inventory turnover ratio of Golden Cup is already higher than the industry's average. That means that Golden Cup's current inventory level is appropriate and increasing it would only result in higher costs but would have very little influence on the company's sales.
