When TIP Tech was first starting up$,$ Tyler loaned $$5,000$ to the company so it could purchase some supplies to make its initial prototypes. Tyler didn't think it was necessary to have a lawyer draw up any documents memorializing the loan, so he wrote a document himself for the company to sign as a promise to repay the loan. The document says, "TIP Technologies promises to pay to Tyler $$5,000,$ plus $10\%$ interest, on a date one year from the date of this instrument." TIP Tech then signed the document. Is this a valid negotiable instrument?
