After the price of good A increased by 30%, the volume of demand for good B increased by 15%. The cross-elasticity

After the price of good A increased by 30%, the volume of demand for good B increased by 15%. The cross-elasticity coefficient of demand for good B at the price of A is ….

Decision:
Ex = ∆Qx% / ∆Qp%
Ex = 15% / 30% = 0.5
Since the cross-elasticity coefficient shows how many percent the volume of demand for one product will change when the price of another product increases by one percent.
