Answer:
$71,400
Step-by-step explanation:
Average cost method uses a simple average of all items as follows:
Total cost = (15000 x 8) + (15000x 10) + (20000 X 12) = $510,000
Total inventory = 15000+15000+20000 =50,000
Average cost = total cost / total inventory = 510000/50000
= $10.2
Cost of ending inventory = 7000 units x $10.2 = $71400
