Bicycle helmets need 0.8 pounds of plastic each and ski helmets 1.6 pounds. Production is 2,640 bicycle and 4,760 ski helmets, desired ending plastic is 90 pounds and beginning plastic is 120 pounds. How much plastic must be bought?

1. Plastic for bicycle helmets is 2,640 units times 0.8 pounds, which is 2,112 pounds. 2. Plastic for ski helmets is 4,760 units times 1.6 pounds, which is 7,616 pounds. 3. Plastic required for production is 2,112 plus 7,616, which is 9,728 pounds. 4. Desired ending inventory of 90 pounds is added, giving total pounds needed of 9,818. 5. Beginning inventory of 120 pounds is deducted, since it is already in stock. 6. Pounds to be purchased are 9,818 minus 120, which is 9,698 pounds. 7. At $4 per pound that is $38,792 of budgeted plastic purchases. 8. 9,818 pounds is the requirement before opening stock is credited, and 9,728 pounds ignores both inventories. _Source: Jonick, Principles of Managerial Accounting (UNG Press, CC BY-SA 4.0), section 7.6 Sales Budget_
