The formula from 3) can be rewritten as Beginning + Purchases = Cost of Goods Sold + Ending. The sum of Beginning + Purchases is often referred to as Available for sale. These items are either sold and costs included in the expense account Cost of Goods Sold or are unsold and remain in Ending inventory. The sum of COGS and ending inventory will always equal the Inventory available for sale and is referred to as inventory accounted for. Return to 3) above and calculate the inventory available for sale for each of the 4 companies:

Daves Doors ____________________ (60,000 beginning + 40,000 purchases)

Bills Bakery ____________________

Shellys Shampoo ____________________
