inventory.
Perpetual system: keep a running balance of inventory, COGS is based on every transaction
Periodic: count once at end of the period

* you can start from calculating 900 units ending balance by grabbing them from the newest
inventory or start from COGS when using FIFO
*WAC= 3200/1400=2.285 because we use periodic, we don’t care when we purchase and sale
Gross profit: revenue-COGS
Revenue=400*5+100*7=2700
