Answer:

$ 21

Step-by-step explanation:

Money spent = (2/5) * 60 + (1/4) * 60

                      = 2*12 + 1*15

                      = 24 + 15

                      = $ 39

Money save = 60 - 39 = $ 21

Using the method of Lagrange multipliers, we have the Lagrangian

L(x,y,z,\lambda_1,\lambda_2)=x+2y+\lambda_1(x+y+z-4)+\lambda_2(y^2+z^2-4)

with partial derivatives (set equal to 0)

L_x=1+\lambda_1=0\implies\lambda_1=-1
L_y=2+\lambda_1+2\lambda_2y=0\implies\lambda_2y=-\dfrac12
L_z=\lambda_1+2\lambda_2z=0\implies\lambda_2z=\dfrac12
L_{\lambda_1}=x+y+z-4=0
L_{\lambda_2}=y^2+z^2-4=0

From L_y and L_z, we find that \lambda_2y=-\lambda_2z\implies y=-z. Then substituting into L_{\lambda_2}, we find

y^2+z^2=4\implies2y^2=4\implies y=\pm\sqrt2\implies z=\mp\sqrt2

and substituting these into L_{\lambda_1}, we get

x+y+z=4\implies x=4

So we have two possible critical points, (4,\pm\sqrt2,\mp\sqrt2), which give extreme values of 4+2\sqrt2 and 4-2\sqrt2, respectively.
