Which one of the following budget items would probably be considered a fixed expense?

None

To determine which budget item would typically be considered a fixed expense, we first need to understand what fixed expenses are. Fixed expenses are recurring costs that remain relatively constant on a month-to-month basis. They do not typically change based on usage or consumption.

Given this definition, let's go through the given options to identify the fixed expense:

1. Rent/Mortgage: This expense is usually considered a fixed expense as it remains constant throughout the duration of a lease or mortgage agreement.

2. Groceries: Groceries can vary from month to month and are usually dependent on individual preferences and family size, making them a variable expense.

3. Entertainment: Entertainment expenses can change based on personal choices and may include activities like movies, dining out, or subscriptions. These expenses tend to vary, making them a variable expense.

4. Utilities: Utilities encompass services like electricity, water, heating, and internet. While they may fluctuate slightly with usage, they are typically fixed expenses as they have a minimum monthly cost that remains constant.

Based on the definitions provided, the most likely fixed expense from the options given would be:
- Rent/Mortgage
- Utilities

Both of these expenses tend to remain relatively stable over time and are not subject to significant fluctuations based on monthly consumption or personal choices.
