Answer:
Option (D) is correct.
Explanation:
Sale from beginning inventory = (Beginning inventory - sales units) × selling price per unit
= (24 - 17) × $15
= 7 × $15
= $105
Sale from September 17th purchase:
= (Beginning inventory - sales units of Sept 5 and Sept 30) × $20
= (24 - 17 - 8) × $20
= 1 × $20
= $20
Therefore,
Cost of good sold on Sept 30 = Sale from beginning inventory + Sale from September 17th purchase
= $105 + $20
= $125
Ending inventory:
= ( Beginning inventory - Sept 5 Sale + Sept 17 Purchase - Sept 30 Sale) × per unit purchasing price
= (24 - 17 + 10 -8) × $20
= 9 units × $20
= $180
