Hi, Ioan, and sorry, but I could not figure it out with formulas. This problem reminds me of "linear programming." Perhaps you can google "excel linear programming" It's a difficult challenge, I think

Hi Ioan

You try use the solver to solve this type of problems.

For ex., in this case you have an exact match: 680 = 4 * 120 + 200
