They are equal! The consumer is happy. If they weren’t equal, you’d reallocate spending until they were. No calculus needed—just division.
subject to the budget constraint. Using the (the derivative of utility), consumers reach an optimum when the ratio of marginal utilities equals the ratio of prices:

The most fundamental concept in microeconomics is the trade-off, mathematically represented by the concept of opportunity cost. This is best illustrated through the Production Possibility Frontier (PPF). Using simple geometry, the PPF plots the maximum possible output combinations of two goods an economy can achieve when all resources are fully and efficiently employed. On a graph, the vertical axis might represent capital goods and the horizontal axis consumer goods. The downward slope of the curve represents the trade-off: to produce more of one good, one must produce less of the other.
Demand represents the consumer's willingness to buy a product at various price points. A typical linear demand curve is written as: Qd=a−bPcap Q sub d equals a minus b cap P Qdcap Q sub d : Quantity demanded : Price of the good : Autonomous demand (quantity demanded when price is zero) between marginal, average, and total costs using a graph
Microeconomics is the study of how individual units—such as households and firms—make decisions and interact within markets. While the field can involve complex calculus, many of its core principles are best understood through simple mathematics, such as basic algebra and geometry, which serve to clarify economic theories. Core Concepts in Simple Mathematical Terms
To avoid getting different elasticities depending on whether price rises or falls, economists use the average of the two points:

Consumers aim to maximize their utility (satisfaction) given their budget constraints. Utility Maximization
A rational consumer maximizes utility where the subjective valuation of the goods matches the objective market prices. Geometrically, this occurs where the indifference curve is perfectly tangent to the budget line:
