Answer: 20,575 pounds
Explanation:
Production needs in February are 20,600 units.
These take a pound of material to be made finished goods so 20,600 pounds are needed.
Raw material purchase = Total required + Closing inventory - Opening inventory
Closing inventory = 25% * March needs
= 25% * 19,300 = 4,825 pounds
Opening inventory = 25% * Feb needs
= 25% * 20,600 = 5,150 pounds
Raw materials purchase = 20,600 + 4,825 - 5,150
= 20,575 pounds
