Answer:
Gross Profit Margin: 53 % and 54%
Inventory days outstanding: 249 days and 252 days.
Explanation:
Gross Profit Margin = Gross Profit / Sales * 100
Gross profit = Sales - Cost of Goods Sold
Gross Profit :
Year 1 : 10,498,448 - 4,860,309 = 5,638,139
Year 2 : 8,277,782 - 3,804,031 = 4,473,751
GP margin :
Year 1 = 53%
Year 2 = 54%
Days of inventory : Average inventory / Cost of Sales * 365 days
Year 1 : 3,320,864 / 4,860,309 * 365 = 249 days
Year 2 : 2,632,898 / 3,804,031 *365 = 252 days
