The maintenance department of an organization has been budgeted $500,000 for the current year's maintenance work. At the end of the fiscal year, the general ledger shows that they have only spent $450,000 on maintenance. To avoid being granted $450,000 the next year, the manager has decided to wastefully spend $5,000. This is an example of

- use-it-or-lose-it mentality

- zero-based budget

- budgetary slack

- imposed budget
