I'm having a problem posting two particular transactions on a general journal sheet.

The transaction is Collected registration fees $16,200.00. Now can this transaction be posted like this Cash $16,200.00 on the debit side and Registration fees $16200.00 on the credit? Or can this transaction be posted in a different way?

The second transaction is Received bill from Bob's restaurant for meals served to campers on account $6,500. Can this transaction be posted as Food expense $6,500 on the debit side and Accounts payable $6500.00 on the credit?

Please help

These 2 transactions are correct.
