None of the above. 15. Which of the following constraints represents the restriction on tubing? a. 20X+25Y 6,000 b. 4X+5Y1,200 c. 25X+20Y6,000 d 5X+4Y

Explanation / Answer

14)
Max Z = 40X + 30Y
b) is correct
15)
20X + 25 Y <= 6000
a) is correct

16)

5X + 4Y <= 1500 ,
20X + 25 Y <= 6000 ,
X +2Y <= 300,
