Answer:
Using COGS
Inventory TurnOver = 19.54
days in inventory = 46.95
Using Sales
Inventory TurnOver = 19.54
days in inventory = 18.68
Explanation:
Inventory TurnOver = COGS or sales / Average Inventory
Were: average inventory = (beginning + ending inventory ) / 2
days in inventory = 365 / Inventory TurnOver
Some accounts work with COGS and some with sales, the latter being more used, but because you have the two option and didn't specifically declare any of the two I will give you answer for both of them, then it will your work to check which one are you using in your course.
Average inventory = (21400+22600 ) /2 = 22,000
Inventory TurnOver (using COGS) = 171,000/22,000 = 7.77
days in inventory (using COGS) = 365/7.77 = 46.97
Inventory TurnOver (using Sales) = 430,000/22,000 = 19.54
days in inventory (using Sales) = 365/19.54 = 18.68
