Suppоse thаt yоu cоnsume Good A аnd Good B. Good A is on the x-аxis, and Good B is on the y-axis. Assume that the price of Good A decreases. • The optimal basket before the price change contains QA = 2 and QB = 4. • The optimal basket after the price change contains QA = 4 and QB = 6. • The optimal basket with the original purchasing power and new price of Good A contains QA = 5 and QB = 1. Based on this information, select the correct statement.
