Answer:
period: 3,700
perpetual: 4,200
Step-by-step explanation:
periodic system:
available goods:
800 + 1000 + 2000 + 800 = 4,600
sales: 1,500 + 1,600 = 3,100
ending inventory 1,500 units
under LIFO we sale the newest units first so the ending inventory is compose of the beginning inventory + oldest purchase:
ending inventory 1,500
beginning inventory (800)
from purchase 700
Ending inventory valuation:
800 x 2 + 700 x 3 = 1,600 + 2,100 = $3,700
Perpetual System:
We evaluate after each sale so:
inventory available at first sale:
beginning 800
2/8 purchase 1,000
sale for (1,500)
ending inventory 300 units of beginning inventory
inventory available at second sale:
beginning 300 units
2/17 purchase 2,000
Sales for (1,600) units
ending inventory:
beginning 300 units x 2 = 600
2/17 purchase 400 units x 1 = 400
+ 2/28 purchase 800 units x 4 = 3,200
total valuation 4,200
