Budget Constraints revisited The constraint p1X1+p2x2=p1o1+p202 s p1(x1-01)+p2(X2-02)=0 That is the sum of the values of a consumer's net demands is zeroBudget Constraints Revisited The constraint is That is, the sum of the values of a consumer’s net demands is zero. p1 (x1 −1 ) + p2 (x2 −2 ) = 0. p1 x1 + p2 x2 = p11 + p22
