The minimum is P = at

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

p max= 22

when x=5 and y=1

p min=0

when x=0 y=0
