How the decrease in price of a complementary y the affect the demand for a commodity x ?

The decrease in price of a complementary good y will generally lead to an increase in the demand for commodity x. Complementary goods are products that are typically consumed together, meaning that the demand for one is influenced by the demand for the other.

When the price of a complementary good y decreases, it becomes more affordable for consumers to purchase. This affordability encourages consumers to buy more of complementary good y, which in turn increases the demand for commodity x. For example, if the price of coffee (complementary good y) decreases, people may be more inclined to buy coffee makers (commodity x) to enjoy their cheaper coffee.

The decrease in price of a complementary good y essentially lowers the overall cost of consuming both goods together, making it more attractive for consumers to purchase both. As a result, the demand for commodity x is positively affected by the decrease in price of complementary good y.
