Adorable junior garment sells merchandise on account to Hudson's Bay on July 1 for $1000 with payment terms of 2/10, n/30. Only July 4, The Bay returns merchandise worth $100 to Adorable Junior Garment. On July 10, Adorable Junior Garment receives payment from The Bay for the balance due/ The journal entries to record these transactions on the books for Adorable Junior Garment are as follows: (picture)

My question is, how would this look like if Adorable Junior Garment used a perpetual inventory system. There will be a second journal entry to record the cost of the goods sold (and the cost of the goods returned) for July 1 and July 4 transactions.
