If the change in quantity is $\Delta y = -3$ and the change in price is $\Delta x = 1$ , what is the absolute value of their ratio $|\frac{\Delta y}{\Delta x}|$ ?

Hint

Concept: absolute-values

The absolute value ignores the negative sign, providing the magnitude of the ratio.

The Problem of Choice

Introduction to the consumer's dilemma: balancing likes and affordability.

By the end of this chapter, you'll be able to solve problems like this: If you only have ₹40 in your pocket, and bananas cost ₹5 each while mangoes cost ₹10 each, what exact combination of bananas and mangoes should you buy to get the maximum possible satisfaction?

This is the fundamental problem of Consumer Behaviour. Every day, we face a budget constraint. We have a limited income, but we want a combination of goods that gives us the highest level of utility (satisfaction).
