4x1+6x2+7x3+8x4=z

s.t.

2x1+3x2+4x3+7x4<=4600

3x1+4x2+5x3+6x4<=5000

x1+x2+x3+x4=950

x4>=400

x1,x2,x3,x4 are integers

I do not have this as optimal

If you consider x3 and x1, for every x3 you increase at the expense of an x1 (trade out) the sales increases and you are still within the constraints meaning more optimal profit.

Here's my try

200 of product 1, 0 of product 2, 350 of product 3, 400 of product 4
