74PRACTICE PROBLEM

Evaluate the objective function, z = 2x + 4y, at each corner of the graphed region. Then, determine its maximum and minimum value.

ANSWERS OPTIONS

z(3, 4) = 18; z(4, 8) = 32; z(7, 7) = 20; z(9, 5) = 46; maximum: z = 46; minimum: z = 18

z(3, 4) = 15; z(4, 8) = 30; z(7, 7) = 25; z(9, 5) = 50; maximum: z = 50; minimum: z = 15

z(3, 4) = 22; z(4, 8) = 40; z(7, 7) = 42; z(9, 5) = 38; maximum: z = 42; minimum: z = 22

z(3, 4) = 27; z(4, 8) = 32; z(7, 7) = 48; z(9, 5) = 52; maximum: z = 52; minimum: z = 27
