Answer: AVERAGE COST = $60.50
Explanation:
January 1:
Inventory unit = 600
Cost per unit = $55
Total cost = $33,000
January 10:
Purchased inventory unit = 1000
Cost per unit = $59
Total = $59,000
January 12:
Unit sold = 1200
January 20:
Purchased inventory unit = 800
Cost per unit = $62
Total = $49,600
Average cost of inventory prior to January 12 sales :
[Cost(January 1) + Cost(January 10)] ÷ unit (January 1) + unit(January 10)
= $(33,000 + 59,000) ÷ (600 +1000)
= $92,000 ÷ 1600 = $57.50
Sales made on January 12: 1200 units
Total units left in inventory :
1600 - 1200 = 400 units
Average cost of inventory after January 20 inventory purchase:
(Unit × cost per unit) ÷ total unit
Average cost =[ (400 × $57.50) + (800 × $62)] ÷ (400 + 800)
Average cost = ($23,000 + $49,600) ÷ 1200
Average cost = $(72,600 ÷ 1200) =
$60.50
