file ProdMix.xls from Canvas $($Look for the Week $2$ Materials in "Modules."$)$ Solve this problem optimally using Excel. Remark: Do not restrict the number of units to be an integer! For this exercise, it is OK to consider the production of fractions of units $($e$.$g$.,$ it is fine if the optimal solution shows that you should produce $34\mathrm{.}65$ tables$).$ If you set your optimization correctly, you will find that the optimal solution for this problem yields an optimal profit of about $$101,773.$ Make sure that you get this value; otherwise, you are likely to mess up the solutions to the following question. What would be the optimal profit if demand was unlimited? In other words, what would be the optimal profit if you could sell any quantities that you can produce?
