Which method or methods listed below describe a solid system for keeping financial records? I. Making a mental note of all purchases made during the week. II. Recording money spent in a hand-held notebook. III. Organizing receipts and transactions on a computer.

A solid record-keeping system uses written or digital records that can be reviewed later. A hand-held notebook records spending, and a computer can organize receipts and transactions. Merely making a mental note is unreliable and does not create a dependable record, so the correct choice is “II and III.”
