Answer:
a point on the demand curve goes down
Explanation:
Complimentary goods are products used together to provide a solution to a customers' need. A complimentary good will not be of any use without its partner product. Complimentary goods exhibit a joint demand. A rise or decline in the demand for one product will result in the demand for the product moving in the same direction.
An increase in the price of a product leads to a decline in its demand and the demand for its complementary goods. A decline in demand leads to a price movement along the demand curve. As prices rise, demand decline resulting in the quantity moving downward along the demand curve.
