75PRACTICE PROBLEM

Evaluate the objective function, z = 25x + 60y, at each corner of the graphed region. Then, determine its maximum and minimum value.

ANSWERS OPTIONS

z(0, 0) = 0; z(0, 10) = 600; z(6, 8) = 630; z(10, 0) = 250; maximum: z = 630; minimum: z = 0

z(0, 0) = 5; z(0, 10) = 480; z(6, 8) = 520; z(10, 0) = 700; maximum: z = 700; minimum: z = 5

z(0, 0) = 0; z(0, 10) = 500; z(6, 8) = 710; z(10, 0) = 450; maximum: z = 710; minimum: z = 0

z(0, 0) = 0; z(0, 10) = 250; z(6, 8) = 620; z(10, 0) = 300; maximum: z = 620; minimum: z = 0
