30r+45d
10r+15d≤1800
20r+25d≤2500
6r+15d≤1500
s.t.
a) Use the Graphical Solution Method to solve the linear
programming problem (label all functions, corner point points, and
axis).
r≥50
2d-1r ≥0
r,d≥0 or all variables non-negative
Note; that the function is optimal at the corner point (75, 70) , hence marking feasible region is independent of solution, however the constraints must be satisfied for optimal solution.
Hope it clarifies your doubt.
Thanks!
