As the price of soup decreases, the quantity of chili that people buy decreases. How do we categorize soup and chill? We categorize soup and chili as __ A. normal goods B. substitutes C. complements D. inferior goods

## Step 1<br />In economics, goods are categorized based on their relationship with each other. The relationship between two goods can be such that when the price of one good increases, the demand for the other good also increases. This is known as a complementary good.<br /><br />## Step 2<br />In this case, soup and chili are considered complementary goods. This is because when the price of soup decreases, the quantity of chili that people buy also decreases. This indicates that the two goods are used together, and a decrease in the price of one good leads to a decrease in the demand for the other good.<br /><br />## Step 3<br />This is different from normal goods, which are goods that see an increase in demand as income rises. It's also different from substitutes, which are goods that can replace each other. Lastly, it's different from inferior goods, which are goods that see a decrease in demand as income rises.
