Constraints: A+B+C=100, A≥0, B≥0, C≥0

What is it exactly you want to plot against what? Because of your constraints this 4D system can be reduced to at least 3D, so you can plot valid (A,B,z) points.
Have a read here and then clarify your question so we can help you along. Right now it is impossible to know if you need surf or solve.
(Oh, and show that you put in effort, people will be more likely to try to help if you do)

N = 10 ;
A = linspace(0,100,N) ;
B = linspace(0,100,N) ;
C = linspace(0,100,N) ;
[A,B,C] = ndgrid(A,B,C) ;
thesum = A+B+C ;
idx = find(thesum==100) ;
z = 100*A(idx) + 75*B(idx)+ 50*C(idx) ;
scatter3(A(idx),B(idx),C(idx),z,z,'.')
