Answer:
Ending inventory= $750
Step-by-step explanation:
To calculate the ending inventory under FIFO (first-in, first-out), we need to use the cost of the last units incorporate into inventory.
Ending inventory:
Sep. 1= 20*20= 400
Sep. 4= (10*20)= (200)
Sep. 10= 30*25= 750
Sep. 17 (20*25)= (500)
Sep. 30= 10*30= 300
Ending inventory= $750
