Please help with journalizing AND posting (the following accounts are used in the ledger: cash, accounts receivable, merchandise inventory, accounts payable, sales, cost of merchandise sold)

Keep in mind the accounts that are used in the ledger must be used when journalizing as well (do not make up accounts) I need postings to journal and ledger, because I am not sure how to complete this. Thank you. Please complete this throughly.
