Answer:
$23.19
Step-by-step explanation:
The the weighted average perpetual inventory system recalculates a new unit cost whenever a new purchase is made. This unit cost is used to value cost of sales and inventory balance.
Unit Cost = Total Cost of units available for sale ÷ Total units available for sale
August 18
Unit Cost = [(19 units x $16) + (21 units x $15)] ÷ 40 units
= $15.475
August 31
Unit Cost = [(2 units x $15.475 ) + (24 units x $19)] ÷ 21 units
= $23.1880 or $23.19
therefore,
The per-unit value of ending inventory on August 31 is $23.19.
