Question

C=5x+2y find the maximum and minimum,show and answer

Answer 1

Explanation:

C=5x+2y

Feasible points are (2,-2),(2,2),(-3,1) and (-1,-2)

at (2,-2) , C=5(2)+2(-2)=10-4=6

at (2,2) ,C=5(2)+2(2)=10+4=14

at (-3,1) ,C=5(-3)+2(1)=-15+2=-13

at (-1,-2) ,C=5(-1)+2(-2)=-5-4=-9

Maximum value is 14 at (2,2) .

Minimum value is -13 at (-3,1)
