Please use constrained optimization (use Lagrange multipliers) to derive individual demand curves and find optimal quantities. I I Let le,, x2) =x12x . the price of x1 equal p1. and the price of x; equal p2. Income equals M. Derive individual demand curves for X1 and X2 in terms of income and prices. What are optimal quantities if p1=4, p2=2, and M equals $1.000
