Complementary goods are goods that are consumed together
If the price of gasoline increases, it would become more expensive to maintain sport utility vehicle. As a result, the demand for sport utility vehicle would decrease. this would shift the demand curve for sport utility vehicle inward.
A increase in the price of gasoline would result in a decrease in the quantity demanded of gasoline and not a reduction in demand.
