In the textbook CH $12,$ we run the Excel Solver to find the optimal answers for the M&D Chemical Company's cost minimization $($starting Slide#$33$ of CH $12$ Lecture PPT$)$:

Test $2$ MD Chem $1.$png

Then, we run the Sensitivity Report $($Slide#$56$ of CH $12$ Lecture PPT$)$:

We can see $"1$E$+30"$ in some cells. It means the value $=\_\_\_\_\_\_(2$ points$)$

In the output of constraints, which constraint is not binding? $\_\_\_\_\_\_\_\_\_(2$ points$)$

If the minimum required total production increases by one unit, how much will the minimum total costs also increase? $\_\_\_\_\_\_\_(2$ points$)$
