Step-by-step explanation:
When Jane borrowed $1,000 from West Bank and signed a promissory note, she became the maker of the note. A promissory note is a financial instrument that contains a written promise by one party (the maker) to pay another party (the payee) a definite sum of money, either on demand or at a specified future date. Jane is legally obligated to repay the amount according to the terms and conditions mentioned in the promissory note.
