You could make $E_1 < E_2$, which would also imply that $P_{Y_1} < P_{Y_2}$ (since $u_{Y_1} < u_{Y_2}$). And of course you could make $E_1=E_2$, which would also imply that $P_{Y_1} < P_{Y_2}$ for the same reason. | |

A question though, does your solution assume that E1 and E2 are different? The problem is unclear in this regard, but given the slope in the linearly elastic region of your graph, it would appear so. Also, I'm not sure why Py2 is less than Py1. Can you explain this? | |
