Answer:

The minimum value of C is 20

Explanation:

we have


2x+3y\geq 24 ----> constraint 1


4x+y\geq 38 ----> constraint 2


x\geq 0 ----> constraint 3


y\geq 0 ----> constraint 4

using a graphing tool

The solution is the shaded area

see the attached figure

To find the minimum value of C evaluate the vertices (9,2) and (12,0) of the solution area in the objective function
C=2x+y

so

For x=9, y=2 --->
C=2(9)+2=20

For x=12, y=0 --->
C=2(12)+0=24

therefore

The minimum value of C is 20
