Question 1123744
<font face="Times New Roman" size="+2">


From a practical point of view, you cannot, from the information given, determine a mixture that would maintain the PROFIT.  There would be labor and perhaps packaging cost, unspecified in your problem statement, resulting from creating the mixture that would be over and above the cost of the raw materials, namely the peanuts and the cashews.  You can, however, find a relation that maintains the REVENUE:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.5(40)\ +\ 4x\ =\ 2(40\ +\ x)]


Where *[tex \Large x] is the weight of cashews to add to the mix to maintain revenue.
