Gross Sales = 400000
 Sales Return = 17500
 Gross Purchases = 250000
 Beginning Inventory = 160000
 Freight In = 8000
 Purchase Return & Allowances = 7000
 Net Sales = Gross Sales - Sales Return
 Net Sales = 400000 - 17500
 Net Sales = 382500
 Gross Margin = 30% of Net Sales
 Gross Margin = 30% of 382500
 Gross Margin = 114750
 Gross Margin = Net Sales - Cost of Goods Sold
 114750 = 382500 - Cost of Goods Sold
 Cost of Goods Sold = 382500 - 114750
 Cost of Goods Sold = 267750
 
 Cost of Goods Sold = Beginning Inventory + Net Purchases - Ending Inventory
 Cost of Goods Sold = Beginning Inventory + (Gross Purchases + Freight In -Purchase Return & Allowances) - Ending Inventory
 267750 = 160000 + (250000 + 8000 - 7000) - Ending Inventory
 267750 = 160000 + 251000 - Ending Inventory
 267750 = 411000 - Ending Inventory
 Ending Inventory = 411000 - 267750
 Ending Inventory = 143,250
