The statement "Trudy was balancing her budget for the current month. She found that her balance was a negative number. She had money left over for next month" is contradictory. If Trudy's balance for the current month is a negative number, it means she has spent more money than she has earned or allocated for expenses. In this case, it would be unlikely for her to have money left over for next month.

Therefore, the statement is:

- False
