** What software would you use to generate this information most efficiently? I used Excel but I'm receiving multiple errors. If you can do this by hand, can you provide me with the best steps? Please, don't just provide the answer, the steps will help me with future questions :)

Show how you would include the following cost functions, C(S), in a linear optimization

model.

1. Fixed = 0, variable = 10,

2. Fixed = 0, variable = 5,

3. Fixed = 0, variable = 8 to S = 5, then 15.

4. Fixed = 20, variable = 5,

5. Fixed = 14, variable = 4 to S = 6, then 12,

6. Fixed = 20, variable = 5 to S = 7, then 3.
