Answer: 3.9 times; an improvement; efficiency
Step-by-step explanation:
Inventory turns is calculated by the formula:
= COGS / Inventory
= 8.4 / 2.50
= 3.36
Increased by 15%:
= 3.36 * (1 + 15%)
= 3.864
= 3.9 times
Inventory turns is used to show how often the inventory was sold in a period. A higher ratio therefore presents increased efficiency and is desired.
