plz answer both thank you

2.5 point A process flows from Station A to Station B, than to Station C, and ends with Station D. Station Atakas 15 minutes to produce one unit Station B produces 3 units per hour. Station producen 4 units per hour. Station takes 12 minutes to produce one unit. Which of the following changes has the greatest not benefit to the total flow? 1. reducing the flow time at Station A to 10 minutes 2. Increasing the capacity at Station 3 to 4 units per hour Increasing the capacity at Station to Sunits per hour O4 reducing the flow time at Station to 10 minutes 2.5 points defined as QUESTION 34 The concept of shadow price show as part of the results of solving a linear programming problem uning a computer program (ika POM), can be 1. Suggestion of where to raise the product prices O2 Marginal improvement in the results of the objective function achieved by relaxing the related constraint by one unit 3: Hidden costs in the objective function caused by opposing constraints 4. Penalty costs from mixing non-negativity with the other constraints 2.5 point A process flows from Station A to Station B, than to Station C, and ends with Station D.
