All other things being equal, when the average price of hybrid SUVs rises from £30,000 £30,000\,£30,000 to £36,000£36,000£36,000, the monthly quantity demanded of all-electric sedans increases from 15,000 15,000\,15,000 units to 18,750 18,750\,18,750 units. Therefore, the cross elasticity of demand (XEDXEDXED) for all-electric sedans with respect to the price of hybrid SUVs is
−0.80-0.80−0.80
+0.80+0.80+0.80
−1.25-1.25−1.25
+1.25+1.25+1.25
