The vertices of the feasible region represented by a system are (0, 100), (0, 80), (80, 60), (80, 0), and (120, 0). what are the minimum and maximum values of the objective function f = 8x + 5y? m

Step-by-step explanation:

F = 8x + 5y

At (0, 100):  F = 8×0    + 5×100 =     0 + 500 = 500

At (0, 80):   F = 8×0    + 5×80   =     0 + 400 = 400 — MINIMUM

At (80, 60): F = 8×80  + 5×60  = 640 + 300 = 940

At (80, 0):   F = 8×80  + 5×0    = 640  +     0 = 640

At (120, 0):  F = 8×120 + 5×0   = 960  +     0 = 960 — MAXIMUM

The minimum value is and the maximum value is .
