Answer:
a. $15.0 million
Step-by-step explanation:
COGS = 66%*Sales = 66% * $273 million = $180.18 million
Old inventory = COGS/Inventory Ratio = $180.18/4 = $45.045 million
New Inventory = COGS/Inventory Ratio = $180.18/6 = $30.03 million
Reduction in inventory = Old inventory - New inventory = $45.045 million - $30.03 million = $15.015 million = $15 million
