Final answer:
The cross elasticity of demand between car insurance and new cars being -0.41 indicates that the two goods are complementary.
Step-by-step explanation:
The cross elasticity of demand between car insurance and new cars being -0.41 indicates that the two goods are complementary. This means that they are consumed together or have a negative relationship in terms of demand. When the price of new cars decreases, the demand for car insurance is expected to increase, and vice versa.
