    Excel solver

    Pls see attached. Anyone have any thought what might be tripping up my solver? I keep running into the same issue where Excel says that the conditions required for a Linear solution aren't met by my (very basic) Excel models. I can use Data Tables to find solutions to these three projects, but I would like to know where I might be going wrong with solver. Others I know have been able to use solver to get solutions for the same models. Problem with Excel solver.xlsx

    Many thanks!

    You have the solving method as "Simplex LP" this is for solutions that are mathematically linear. Your setup is not linear

    Change the method to "GRG Non-linear" and you should not get the error.

    PS when I use solver for 3 Problems I get
    A:36.2274653072142 at a price of -7662.26

    B: Price of 21 for a profit of 180500

    C: Price of 4.48022927114475 for 222.30
