Answer 23

ok ty

Answer 24

With question 23 I'd say substitute appropriate values for x and y
C = 5x -y
so that
x>=0
y>=5
and x+y <= 12

Answer 25

wait i dont understand

Answer 26

For x>=0 ,
x can be 0 , 1, 2, 3, etc

y>=5
y can be 5, 6, 7, 8, 9 10

x+y <= 12
This limits your choices for x and y since their total must be 12 or less than 12

Answer 27

so is the answer less than 12?

Answer 28

For the minimum value, x would be 0 and y could be 12 so the value of c
would be -24
Working on the maximum value now .........

Answer 29

For a maximum value, we choose y =5
x can be no larger than 7 because x+y would be greater than 12
so the maximum value would be
c = 25
So the correct answer is the third one down
