Solve the linear programming problem by the method of corners.

Find the minimum and maximum of P = 4x + 2y subject to
 3x + 5y ≥ 20 3x + y ≤ 16 −2x + y ≤ 4 x ≥ 0, y ≥ 0.

The minimum is P =  at

(xy) =
.

The maximum is P =  at
(xy) =
.

Thank you for the opportunity to help you with your question!

3x+5y>=20------------(1)

-3x-y>=-16---------(2)

2x-y>=-4------------(3)

(1)+(2)

4y>=4

y>=1

y max=1

3x+5*1=20

x>=5

x max=5

p max=4*5+2*1

=22

p min=4*0+2*0

=0

Please let me know if you need any clarification. I'm always happy to answer your questions.

p max= 22

when x=5 and y=1

p min=0

when x=0 y=0
