Answer:

minimum value of C is,

C = 14

Explanation:

2x + y ≥ 20 (1)

2x + 3y ≥ 36 (2)

by subtracting equation (2) from equation (1)

2x + y ≥ 20

2x + 3y ≥ 36

- - -

__________

-2y ≥ -16

y ≥ 8

by substituting the value of y in equation (1)

2x + 8 ≥ 20

2x ≥ 20 - 8

2x ≥ 12

x ≥ 6

as we have to find the minimum value of C so we will take the minimum values of x and y which according to inequalities will be,

x = 6

y = 8

thus, the minimum value is:

C = x + y = 6 + 8 = 14
