While some advanced courses require calculus, a "simple mathematics" approach typically utilizes:
When plotted, this equation forms a straight line where the intercepts represent how much of each good a consumer could buy if they spent all their income on that single good. The slope of this budget line represents the relative price of the goods. To model preferences, economists use indifference curves—contour maps that connect points representing equal utility for the consumer. The solution to the consumer’s problem is found where the indifference curve is tangent to the budget line. This tangency condition, which can be understood geometrically as the point where two curves touch without crossing, explains how consumers allocate their income to maximize satisfaction. It provides a logical proof for the Law of Demand: as prices rise, the budget line rotates inward, and the consumer adjusts their consumption to a new, lower quantity demanded. microeconomics with simple mathematics pdf
