How would an increase in the price of peanut butter likely affect the demand for jelly, assuming they are complementary goods?

When the price of peanut butter goes up, people might buy less peanut butter because it costs more. Since peanut butter and jelly are complementary goods, which means they are often used together, this decrease in peanut butter purchases can lead to a decrease in jelly purchases as well. For example, if someone usually makes a peanut butter and jelly sandwich for lunch, they might decide not to buy jelly if they can't afford peanut butter anymore. Therefore, as peanut butter becomes more expensive, the demand for jelly is likely to go down too. This shows how the prices of complementary goods can directly affect each other.
