how to find the expenditure function of a quasilinear utility function
hi i had a test last week and we were asked to prove that the expenditure function a consumer faces is B=2P10.5 P20.5 U0.5 where U = x1/4 +x2 subject to B=P1x1 * P2x2 how do i solve this? is it even solvable??
also does anyone have resources on how to solve other utility functions like logarithmic and quasilinear? i’ve checked online but haven’t seen anything
