When the price of good B rises, the demand for good A decreases. What is the relationship between the two goods? Good B is a ______ good A because the demand for good A and the price of good B change in A. complement of; the same direction B. substitute for; the same direction C. complement of; opposite directions D. substitute for; opposite directions Well done! When a change in the price of good B leads to a change in the demand for good A, good B is either a substitute for or a complement of good A. When the price of good B rises, the quantity demanded of good B decreases. The price of good B and the demand for good A change in opposite directions, so good B is a complement of good A. 3 tries left When the price of good B rises by 2 percent, the demand for good A decreases by 8 percent. Calculate the cross elasticity of demand for good A with respect to the price of good B. The cross elasticity of demand is Type
