Answer:
$1,000
Step-by-step explanation:
As we know that
Cost of material used = Beginning balance of inventory + purchase made during the month - ending balance of inventory
$900 = $200 + purchase made during the month - $300
$900 = -$100 + purchase made during the month
So, the purchase made during the month would be
= $900 + $100
= $1,000
We simply added the purchase to the beginning inventory and deduct the ending inventory
