Costs that do not vary with output quantity divided by the quantity of output is best described by which term?

Total cost is the sum of fixed and variable costs associated with production. Unlike average fixed cost, total cost varies with output quantity since variable costs change with the level of production. Therefore, total cost does not specifically describe costs that remain constant per unit as output changes.

Marginal cost refers to the additional cost incurred from producing one more unit of output. It is primarily concerned with variable costs and how they change with production levels, making it irrelevant to the calculation of costs that do not vary with output, which is the essence of average fixed cost.

Average variable cost is determined by dividing total variable costs by the quantity of output. Unlike average fixed cost, this measure fluctuates with changes in production levels, as it includes only costs that vary with output. Therefore, it does not represent costs that remain unchanged regardless of production volume.
