Sorry, that means nothing to me. A language or translation problem perhaps. I don't know what you mean by anti A, anti B, etc, or where %A, %B came from, or what you mean by "solution exhaust".
i am studying mathcad... thank you for your helps... i know my language is bad.. sorry.. i prepare a mathcad page for my question... thank you for your interest...

Same as Richard.
Your "Fuel", ..."Save as " Mathcad 11 or lower, then lot more collabs will look at it.
Yes, in principle that is solvable. The best approach depends on the nature of the data. You need to fit a multidimensional surface to the data, and then find the maximum of the surface. One such surface could be a polynomial, in which case you can use regress. You could also fit an arbitrary equation using minerr. The problem with the example you have posted is that you have only 5 "measured" values. That means the surface equation cannot have more than 5 coefficients, which is not a lot when you have 4 independent variables. It is enough to fit a surface, but not enough to fit a surface that would give you a realistic answer to your problem.

The "Fuel" project is missing a data set. You have the parts% for each mixture "Fuel", you have the "Pwr" but you don't have the cost ... I have added a working cost "mix". However the "mix" must be in increasing order, that may oblige to re-arrange the "Fuel" array. The sheet includes a metafile picture of what it looks like from my guesses. If you don't have the DAEP [Data Analysis Extension Pack] it will turn red because Bicubic2D is a built-in function delivered with that pack. At least, you can see what the project would look like.

Can't help: you have ABC only ... whatever it means. For the surface plot you need two more data set as demonstrated in my previous post. You are trying to apply methods that don't apply. For the project in case, you will surely find some chemical balance equation [binary diagram] already done by chemist. At any point a project starts, all previous material/matters must be true.

Can't help that more than the other one before . You don't have a matrix of values for each experiment. The multivariate fit is only like a sheet of paper either flat, bent or twisted. A sheet of paper does not make balloon.
