1. The figure shows the solution provided by GAMS of a profit maximization model in a bag production process. The bags need three processes: cutting, sealing, and packaging, which have a limited time weekly, additionally, it is assumed that there are no market restrictions, that is, everything produced is sold.

Taking into account that this problem has three associated dual variables, their respective values, preserving the order of the constraints, are:

A. y1 = -3,333; y2 = -5; y3 = 0 B. y1 = 1; y2 = 6,667; y3 = 0 C. y1 = 6.667; y2 = 0; y3 = 0 D. y1 = 3.333; y2 = 5; y3 = 0 E. None of the above

2. The company is considering acquiring a new machine, which would expand the capacity of the sealing area to 15000 hours per week, this capacity will cost $ 2 per hour. In this case, should the company buy this new machine based on the variation of the objective function?

A. Yes, since for every extra hour in this workstation the objective function improves by 5 units. B. No, since for each overtime at this workstation the objective function decreases by 5 units. C. No, as there are currently 3,600 hours left on this workstation D. No, as there are currently 2400 hours left on this workstation E. None of the above
