I solved the other four problems now but need to write up the solutions.

For the first problem we needed to use a software the professor provided that was not very good. I did get some printouts done for that problem. I seems to have done it correctly but used some common sense about exhanges and ratios rather than the software. The second through fourth problems are very simple because the constraints are large enough to find a simple solution that can be described in words. But I must also use math. So now that I have these three problems solved, I must write them up in LaTeX. I will do this later this evening. I am just going into work in half an hour early again.
