D1 Linear Programming
The question asks to maximise P=3x+2y
subject to
x+y ≤ 8
x+3y ≤ 21
4x+y ≤30
x, y greater than or equal to zero
I used the simplex method and got x=22/3 and y= 2/3
However, I can't do it graphically. There seems to be no feasible region.
I just realised y is a less than so I want the shaded part
Here's a link to the graph http://www.mathway.com/graph/NzI3Nzg

If you draw the graph out a little larger, the feasible region will be made more explicit I'm sure
