Explanation:

Giving the following information:

Ferris Company began January with 7,000 units of its principal product. The cost of each unit is $8.

Merchandise transactions for January are as follows:

Jan. 10: 4,000 units at $ 9 = $ 36,000

Jan. 18: 7,000 units at $10 = 70,000

Totals: 11,000 units for 106,000

Sales:

Jan. 5: 3,000

Jan. 12: 1,000

Jan. 20: 4,000

Total: 8,000

10,000 units were on hand at the end of the month.

A) FIFO (first-in, first-out)

Inventory = 3,000*9 + 7,000*10 = $97,000

COGS = 7,000*8 + 1,000*9 = $65,000

B) LIFO periodic.

Inventory=7,000*8 + 3,000*9 = $83,000

COGS = 7,000*10 + 1,000*9 = 79,000

C) LIFO, perpetual.

COGS = 3,000*8 + 1,000*9 + 4,000*10 = $73,000

Inventory = 4,000*8 + 3,000*9 + 3,000*10 = $89,000

D) Average, periodic.

Purchase cost = (8+9+10) / 3 = 9

Inventory = 10000*9 = $90,000

COGS = 8,000*9 = $72,000

E) Average.

COGS = 3,000*8 + 1,000*8.5 + 4,000*9 = $68,500

Inventory = 72,000
