Answer:
$440 per unit
Step-by-step explanation:
Units balance after July 12 sales = 100 - 70 = 30
Total units after July 23 = 30 + 120 = 150
Total cost of units balance after July 12 sales = $400 × 30 = $12,000
Total cost of July 23 purchases = 120 × $450 = $54,000
Total cost of inventories after July 23 = $12,000 + $54,000 = $66,000
Weighted average unit cost after the July 23 purchase = $66,000 ÷ 160 = $440 per unit
