Question 16 .2 out of 2 points The Wiethoff Company has a contract to produce 10000 garden hoses for a customer. Wiethoff has 4 different machines that can produce this kind of hose. Because these machines are from different manufacturers and use differing technologies, their specifications are not the same.

Write the constraint that indicates they can purchase no more than 3 machines.
Answer
Selected Answer: Y1 + Y2 + Y3+ Y4 ≤ 3
Correct Answer: Y1 + Y2 + Y3+ Y4 ≤ 3 . Question 17 .2 out of 2 points Max Z = 5x1 + 6x2
Subject to: 17x1 + 8x2 ≤ 136 3x1 + 4x2 ≤ 36 x1, x2 ≥ 0 and integer
What is the optimal solution?
Answer
Selected Answer: x1 = 4, x2 = 6, Z = 56
Correct Answer: x1 = 4, x2 = 6, Z = 56 . Question 18 .2 out of 2 points The Wiethoff Company has a contract to produce 10000 garden hoses for a customer. Wiethoff has 4 different machines that can produce this kind of hose. Because these machines are from different manufacturers and use differing technologies, their specifications are not the same.

Write a constraint to ensure that if machine 4 is used, machine 1 will not be used.
Answer
Selected Answer: Y1 + Y4 ≤ 1
Correct Answer: Y1 + Y4 ≤ 1 . Question 19 .2 out of 2 points Max Z = 3x1 + 5x2
Subject to: 7x1 + 12x2 ≤ 136 3x1 + 5x2 ≤ 36 x1, x2 ≥ 0 and
