Thus, utility theory assumes that any decision is made on the basis of the utility maximization principle, according to which the best choice is the one that provides the highest utility (satisfaction) to the decision maker.
In the former case, a utility function is used to derive a numerical score for each choice that represents the utility of this choice.
For instance, a utility of 100 units towards a cup of tea is twice as desirable as a cup of coffee with a utility level of 50 units.

The doctrine of utilitarianism saw the maximisation of utility as a moral criterion for the organisation of society.
Utility was originally viewed as a measurable quantity, so that it would be possible to measure the utility of each individual in the society with respect to each good available in the society, and to add these together to yield the total utility of all people with respect to all goods in the society.
The concept of cardinal utility suffers from the absence of an objective measure of utility when comparing the utility gained from consumption of a particular good by one individual as opposed to another individual.

If the value of the utility function were to be, for example, doubled, squared, or subject to any other strictly monotonically increasing function, it would still describe the preferences correctly.

 Utility function - Information from Reference.com
Utility is applied by economists in such constructs as the indifference curve, which plots the combination of commodities that an individual or a society requires to maintain a given level of satisfaction.
Ordinal utility functions are equivalent up to monotone transformations, while cardinal utilities are equivalent up to positive linear transformations.
The first important use of the expected utility theory was that of John von Neumann and Oskar Morgenstern who used the assumption of expected utility maximization in their formulation of game theory.

 The Paretian System: IV - Social Welfare
The Paretian tide of the 1930s rolled in on the back of the Hicks-Allen ordinal utility function, where the "number of utils" is not clearly a number at all, much less one that can be ascertained and manipulated by an external observer.
As utility is not comparable across individuals, then the choice of social optimum is necessarily a normative concern, a value judgment and thus it is not within the scope of economic "science".
The "utility possibilities frontier" (UPF) and the "grand utility possibilities frontier" (GUPF) were introduced into economics by Maurice Allais (1943), who originally called it the "surface de rendement maximum" (Allais, 1943: p.641) and, later, renamed it the "surface d'efficacité maximum" (Allais, 1989: p.45).

The primary goal of this experiment is to introduce students to the utility maximizing rule and to convince them that whether individuals know anything about economic principles or not they will act to maximize their utility subject to constraints in each of their purchases or activities.
Then they should record the marginal utilities (although you have not yet referred to them using this terminology) using the -100 to +100 scale after considering, when appropriate, their maximum willingness to pay to avoid the activity or the monetary cost of the activity.
In-other-words, if you get 12 utils per dollar of utility from the fourth and last ice cream cone that you buy (the one at the margin), the 12 utils is the change in total utility derived from the ice cream, not the value from the last lick.

A utility function is simply a formula that, for each possible bundle of goods, yields a number that represents the amount of satisfaction provided by that bundle.
To answer this question, we must introduce the concept of marginal utility (the marginal utility of a good is the rate at which total utility changes with consumption of the good) which is the rate at which total utility changes as the quantities of food and shelter change.

A is preferred to B. Note: With ordinal utility, the ordering, or ranking, of the consumer’s preference matter.
At this point, the utility/$ for Good X is equal to the utility/$ for Good Y. This is a stable equilibrium so there is no incentive for the consumer to alter his/her quantities of the two goods.
At this point, the utility/$ for Good X is greater than the utility/$ for Good Y. The consumer will be motivated to adjust his/her quantities of the two goods so as to increase his/her total utility.

The consumer's utility function u : X \rightarrow \textbf R assigns a happiness score to each package in the consumption set.
Note that for u to be a utility function on X, it must be defined for every package in X. A utility function u : X \rightarrow \textbf{R} rationalizes a preference relation <= on X if for every x, y \in X, u(x) <= u(y) if and only if x <= y.

The utility function over lotteries U thus logically precedes the elementary utility function: the latter is derived from the former.
Consequently, the utility function U: R itself is an ordinal utility function since any increasing transformation of U will preserve the ordering on the lotteries.
Thus, in von Neumann-Morgenstern theory, we have a "cardinal utility which is ordinal", to use Baumol's (1958) felicitous phrase.

The utility generated by work clearly changes over time (typically decreases as the challenge decreases within a role) and their utility from other activities changes also (for example having a child might increase the utility derived from staying at home, or maybe have the opposite effect depending on your propensity to enjoy crying).
