quiz\nwhich of the following is a fixed expense for marias sandwich food truck?\nsalaries for her…

Brief Explanations:

Fixed expenses are costs that do not change with the level of production or sales. Salaries for employees are usually set amounts paid regularly. Truck insurance is a recurring cost that doesn't vary with the number of sandwiches sold. Advertising costs can be variable (e.g., pay - per - click ads) or fixed (e.g., a long - term billboard contract), but considering the other two are fixed, and the nature of typical food truck operations, all can be considered fixed in many cases.

Answer:

D. All of the above
