@allyphoe:

I could be wrong, and I apologize if so, but I really don’t think that that is correct. See this link and note that first example lists the total quantity used and is in the format of the equations I posted above:

[SYSTEMS OF EQUATIONS](SYSTEMS OF EQUATIONS)

That’s why I think that you need to know how many bars were used in total before finding how many of each type were used.
