Answer:
$115
Step-by-step explanation:
The computation of the cost of the ending inventory is shown below:
Total units purchased
= 7 units + 5 units + 6 units
= 18 units
And, the total cost is
= 7 units × $8 + 5 units × $10 per unit + 6 units × $11 per unit
= $56 + $50 + $66
= $172
And, the closing units inventory units is
= 18 units - 6 units
= 12 units
So, the cost of ending inventory is
= $172 × 12 units ÷ 18 units
= $115
