# How do I normalize a weighted scoring grid?

I have created a weighted scoring grid that looks something like this

        Factor 1 (weight of 5, scored either 3,6 or 9)        Factor 2 (weight of 4, scored either 3, 6 or 9)


Question 1
Score of 6 for Factor 1
Score of 9 for Factor 2
Total Score of (5*6)+(4*9)=66

Question 2
Score of 3 for Factor 1
Score of 6 for Factor 2
Total Score of (5*3)+(4*6)=39

How do I put the score of 66 and 39 into a more understandable scale of say 1-10 or 1-20?
