is defined as the perception of the benefits associated with a good, service, or bundle of goods and services in relation to what buyers are willing to pay for them.

The answer is Value

Explanation:

Value is the way which buyers regard the usefulness of a particular good, service or a bundle of goods and services. As such, If a particular service or good is regarded by a buyer as 'fairly useful', such a buyer would be inclined to pay less.

On the other hand, if a buyer regards a particular service or good as 'very useful', such buyer would be inclined to either meet the cost of the good or service and might even pay higher than the cost.
