Optimisation Problem

    No this is not homework.

    Ok i am struggling to even start this question.

    I see it has a constraint so i would be tempted to use Lagrangian but from there i don't see how px and qy fit into it?

    Some assistance on the tools needed to approach this question would be great, it may be two-variable optimisation but i don't really have a handle on that either.

    Thanks,

    Josh

    It looks like Lagrange multiplier theory would come in handy. Look at the intro to this Wikipedia page...

    That is exactly your problem (for suitable f, g and c).

    Note that px is just one of the given constants p multiplied by the variable x, I'm not sure why that confuses you.
