Final answer:
The cross-price elasticity of demand for bacon and eggs is negative because they are typically consumed together as complement goods. A price increase in one would likely lead to a decrease in the demand for the other.
Step-by-step explanation:
The cross-price elasticity of demand for bacon and eggs would indeed be negative, because these goods are complements for many consumers. This is true as bacon and eggs are often consumed together, and an increase in the price of one would likely lead to a decrease in the quantity demanded of the other.
When two goods are complements, they are used together, meaning that consumers typically buy both items as a pair. An example of complement goods beyond bacon and eggs is coffee and sugar. If the price of coffee goes up, the demand for sugar may also decrease because people might purchase less coffee and therefore need less sugar to go with it. Similarly, if the price of bacon were to increase, it's likely that the demand for eggs might decline as well, since many people enjoy them as a set.
