Answer:
a. $2,200,000
Explanation:
We solve considering the inventory identity:
[tex]$Beginning Inventory + Purchase = Ending Inventory + COGS[/tex]
[tex]$ Purchase = (Ending Inventory - Beginning Inventory) + COGS[/tex]
the difference during the year means the difference between ending and beginning inventory was of 200,000
So we plug that into the formula and solve
[tex]$ Purchase = +200,000 + 2,000,000 [/tex]
Purchase 2,200,000
