Reversed Weighted Average Formula

Hello,
First timer posting, so I apologize for anything I did incorrectly. I am needing some assistance with weighted formulas. What I am trying to do is rank my employees based on certain metrics. They are weighted in three different catagories. Talk time is 40%, Quality 50%, Attendance is 10%. I can weight the Talk Time and Quality, as those are basically the higher the score the better the weight. Attendance is the opposite, the lower the number, the higher the weight. Meaning, if employee has 1 absence that would better than someone who is at 4 absences. Is there a way to do this. I am somewhat educated on VBA, I understand if,then,else statements and/or Select/Case statements, so if I needed to do it in VBA I can. I just need direction to get it going. Thank you in advance.
