Answer:
Periodic system: FIFO ; COGS= $11400, closing inventory = $7700, gross profit=$14000. LIFO = closing stock= 6600, COGS=$12500, gross profit=12900.
perpetual system: FIFO ;COGS=11400, closing stock= $7700, gross profit= $11400. LIFO ; COGS=$12500, closing stock= $6600, gross profit = $12900
Reason for a higher gross profit in FIFO than LIFO is some of the stock ends up not being sold as they are maybe old, out-fashioned, and obviously new trend come about everyday.
