Answer:
0.0
Step-by-step explanation:
The calculation of cross-price elasticity is given below:-
cross-price elasticity
= change in quantity demand in product B ÷ Change price in product A
= 0% ÷ 30%
= 0.0
Therefore, the quantity demanded does not change in product B because a change in price of product A, so there is no relationship between A and B. Cross price elasticity of demand deals with the change in quantity demand in product B with respect to change in price A.
