Answer and Explanation:

Ferris Company

1. Average cost periodic

Dollars $48,000+$ 105,000

= $153,000

Units $11,000+$6,000

= $17,000

153,000 / 17,000 = $9.00 Cost per unit

Cost of Goods Sold:

9,000 units × $9.00= $81,000

Ending Inventory:

8,000 units × $9.00= $72,000

2. Average cost perpetual Jan 5th sales

Dollars 48,000

Units 6000

48,000 / 6,000 = $8.00 Cost per unit

Cost of goods Sold:

3,000 units × $8.00= $24,000

Ending Inventory:

3,000 units × $8.00= $24,000

3. Average cost perpetual Jan 12th sales

Dollars 69,000

Units 8000

69,000 / 8,000 = $8.625 Cost per unit

Cost of Goods Sold:

2,000 units × $8.625

= $17,250

Ending Inventory:

6,000 units × $8.625

= $51,750

4. Average cost perpetual Jan 20th sales

Dollars 60,000+51,750

=111,750

Units 6000+6000

=12,000

111,750 / 12,000 = $9.3125 Cost per unit

Cost of Goods Sold:4,000 units ×$9.3125= $37,250

Ending Inventory:8,000 units × $9.3125= $74,500

Summary of Average Cost Perpetual

Cost of Goods Sold:

Jan 5 3,000 units= $24,000

Jan 12 2,000 units= 17,250

Jan 20 4,000units = 37,250

Total 9,000units = $78,500
