If the price of a complement decreases, what

happens to the demand for the product being

graphed?

Demand will rise.

Explanation:

Complement goods are products used together to meet a particular need. Examples of complementary goods include tea and sugar, printer and Ink Cartridges, cars and petrol.

If the prices of a complement good fall, then the demand for the other commodity increases. It will be cheaper for consumers to use both goods together. For instance, if the price of sugar falls, consuming tea will be less expensive, which increases its demand.
