Illustrate and explain the changing demand for big mac using theindefference curve and bubget line?

To illustrate the changing demand for a Big Mac using indifference curves and a budget line, we can depict consumer preferences for two goods: Big Macs and another food item. The budget line represents the combinations of these goods that a consumer can afford, given their income and the prices of the goods. As the price of Big Macs decreases, the budget line pivots outward, allowing consumers to purchase more Big Macs, shifting their consumption to a higher indifference curve where their overall satisfaction increases. Conversely, if the price rises, the budget line pivots inward, leading to a decrease in Big Mac consumption and potentially lower satisfaction as consumers move to a lower indifference curve.
