er 21 Homework X 553/quizzes/3326596/take Zavadil was filling out a check. She had gotten so far as to write Prussing's name as payee and sign it. Just then the doorbell rang, so Zavadil stuck the form in her desk drawer and answered the bell. Later Prussing visited Zavadil and found the incomplete check in the desk. Prussing secretly took it, inserted the amount of $5,000 and took it to Prussing's bank to cash it. Assuming Zavadil has more than $5,000 in her checking account, should the check be effective so that Prussing can demand payment of it for $5,000
