[Uses the Marginal Utility Approach] Anita consumes both pizza and Pepsi. The following tables show the amount of utility she obtains from different amounts of these two goods: $$\begin{array}{cc} {}{\quad\quad\quad\quad\quad}{\text {Pizza }} \\ \hline \text { Quantity } & \text { Utility } \\ \hline \text { 4 slices } & 115 \\ \text { 5 slices } & 135 \\ \text { 6 slices } & 154 \\ \text { 7 slices } & 171 \end{array}$$ $$\begin{array}{cc} \quad\quad{}{} {\text { Pepsi }} \\ \hline \text { Quantity } & \text { Utility } \\ \hline 5 \text { cans } & 63 \\ 6 \text { cans } & 75 \\ 7 \text { cans } & 86 \\ 8 \text { cans } & 96 \end{array}$$ Suppose Pepsi costs $\$ 0.50$ per can, pizza costs $\$ 1$ per slice, and Anita has $\$ 9$ to spend on food and drink. What combination of pizza and Pepsi will maximize her utility?

Key Concepts

Marginal Utility

Marginal utility refers to the additional satisfaction or benefit a consumer receives from consuming one extra unit of a good or service. This concept is central in consumer choice theory, where it is used to assess how consumers allocate their resources by comparing the extra utility derived from each additional unit of consumption.

Marginal Utility per Dollar

Marginal utility per dollar is the measure of additional utility gained per unit of currency spent on a good. It is derived by dividing the marginal utility of a good by its price, and it is crucial for determining the optimal consumption bundle. Consumers maximize their overall satisfaction by equalizing the marginal utility per dollar across all goods, ensuring that each dollar spent yields the highest possible additional utility.

Budget Constraint

The budget constraint represents the limited amount of income or money a consumer has available to spend on various goods and services. It is depicted as a line or equation that encapsulates the trade-offs a consumer faces when deciding how to allocate their resources, ensuring that the total expenditure does not exceed their available budget.

Utility Maximization

Utility maximization is the process by which consumers choose the combination of goods that provides the highest total satisfaction or utility, subject to their budget constraints. This involves comparing the marginal utilities of different goods relative to their prices and making adjustments until an equilibrium is reached, where no reallocation of spending can further increase overall utility.

Optimization under Scarcity

Optimization under scarcity involves making the best possible decisions about resource allocation when resources, such as income, are limited. In the context of consumer behavior, it entails selecting the combination of goods that maximizes satisfaction while adhering to budget limitations, often requiring trade-offs based on marginal benefits and costs.
