Answer:
$640
Step-by-step explanation:
Calculation for the value of ending inventory using average-cost method
Value of ending inventory=[(2,600÷30 units+80 units+20 units)*35]
Value of ending inventory=[($2600 ÷ 130) × 35]
Value of ending inventory=$20×35
Value of ending inventory=$640
Therefore Using the average-cost method, the value of ending inventory is $640
