Marshalian and Hickisian Demands and Slutsky Equation
Although my teacher has yet to verify my solution for d) (which I believe is incorrect), he shared his answer and the condition $x_2&lt;k$ derives from the positivity of $V(p_1,p_2,b)$ and from the budget inequality $p_1x_1+p_2x_2≤b$. The other answers are correct.
