Explanation / Answer

Beginning Inventory = 40 units @ $40 = $1,600

Purchases:
June 4 = 135 units @ $44 = $5,940
June 18 = 55 units @ $46 = $2,530
June 28 = 30 units @ $50 = $1,500

Purchase Return:
June 18 = 10 units @ $46 = $460

Cost of Goods available for Sale = Beginning Inventory + Purchases - Purchase Return
Cost of Goods available for Sale = $1,600 + $5,940 + $2,530 + $1,500 - $460
Cost of Goods available for Sale = $11,110

Number of units available for sale = 40 + 135 + 55 - 10 + 30
Number of units available for sale = 250

Sales:
June 10 = 110 units @ $70 = $7,700
June 25 = 65 units @ $75 = $4,875

Sales Return:
June 11 = 15 units @ $70 = $1,050

Number of units sold = 110 - 15 + 65
Number of units sold = 160

Net Sales = Sales - Sales Return
Net Sales = $7,700 + $4,875 - $1,050
Net Sales = $11,525

Number of units in Ending Inventory = Number of units available for sale - Number of units sold
Number of units in Ending Inventory = 250 - 160
Number of units in Ending Inventory = 90

LIFO:

Ending Inventory = 40 * $40 + 50 * $44
Ending Inventory = $3,800

Cost of Goods Sold = Cost of Goods available for Sale - Ending Inventory
Cost of Goods Sold = $11,110 - $3,800
Cost of Goods Sold = $7,310

Gross Profit = Net Sales - Cost of Goods Sold
Gross Profit = $11,525 - $7,310
Gross Profit = $4,215

Gross Profit Rate = Gross Profit / Net Sales
Gross Profit Rate = $4,215 / $11,525
Gross Profit Rate = 36.57%

FIFO:

Ending Inventory = 30 * $50 + 45 * $46 + 15 * $44
Ending Inventory = $4,230

Cost of Goods Sold = Cost of Goods available for Sale - Ending Inventory
Cost of Goods Sold = $11,110 - $4,230
Cost of Goods Sold = $6,880

Gross Profit = Net Sales - Cost of Goods Sold
Gross Profit = $11,525 - $6,880
Gross Profit = $4,645

Gross Profit Rate = Gross Profit / Net Sales
Gross Profit Rate = $4,645 / $11,525
Gross Profit Rate = 40.30%

Average Cost:

Cost per unit = Cost of Goods available for Sale / Number of units available for sale
Cost per unit = $11,110 / 250
Cost per unit = $44.44

Ending Inventory = 90 * $44.44
Ending Inventory = $4,000

Cost of Goods Sold = Cost of Goods available for Sale - Ending Inventory
Cost of Goods Sold = $11,110 - $4,000
Cost of Goods Sold = $7,110

Gross Profit = Net Sales - Cost of Goods Sold
Gross Profit = $11,525 - $7,110
Gross Profit = $4,415

Gross Profit Rate = Gross Profit / Net Sales
Gross Profit Rate = $4,415 / $11,525
Gross Profit Rate = 38.31%
