If a consumer's demand for a luxury car is elastic, then a price increase will likely lead to a decrease in total revenue. In analogy, if the demand for a basic necessity like bread is inelastic, then a price increase will likely result in an increase in total revenue. Therefore, the relationship can be described as: Luxury Car:Price Increase :: Bread:?

When we say that a consumer's demand for a luxury car is elastic, it means that if the price of the car goes up, many people will buy fewer cars or choose not to buy one at all. This leads to a decrease in total revenue because the loss in sales outweighs the higher price. In contrast, bread is a basic necessity, and its demand is inelastic, meaning that even if the price increases, people still need to buy it, so total revenue goes up. For example, if the price of bread rises, families will still purchase it because they need it for meals, resulting in more money for the sellers. Thus, the relationship can be described as Luxury Car:Price Increase :: Bread:Price Increase.
