    maybe have to do: y = 60,000 -x and x = 60000 -y in place of that 60,000; but that still dont seem right to me....

    S = 90x ^1/4 y^3/4 are the constraints of x +y =60,000 F( x,y, *) = f( x,y) - * ( g(x,y)- c)

    whats your gut tell you about what to do with: S= 90 x^1/4 y^3/4 ?? Can we derive this with respect to "S" ? And dont trust my judgement on this, cause its a little above me at the moment :)
