Weighted Average with Multiple Variables

Hey everyone, new here to the forum.

Have a question regarding weighted averages.
I have 5 Variables to consider that will determine the overall score. I will give hypothetical values to use as examples.

1st 95% (holds 80% of total score) - this is a percentage value and of course the higher the percentage the more positive the impact should be on the overall score

2nd 2 points (5% of total score) - these points should negatively effect the overall score
3rd 1 point (5% of total score) - these points should negatively effect the overall score
4th 3 points (5% of total score) - these points should negatively effect the overall score

5th 10 Points (5% of total score) - these points should positively effect the overall score

I want these 5 variables to determine the final score.
Thoughts?

You assumed correctly. and this is basically exactly what I have done I guess I was just doubting my methods lol
Thank you very much for your quick response!

Hi,
First of all I would like to thank you both of you for sharing this excellent details.
As I got the perception that you are master in this kind of mathematical challenges, I ask your help for a very similar challenge: after making an online survey available, I intend to implement the calculation of a user satisfaction index (0 - 100) for users to respond, composed only by 3 possible evaluations (Positive, Neutral or Negative).
The point is that the number of users who choose to answer / rate or not is always unpredictable, which can be 10 on any given day and 1000 or 500 or 20000 on another day.
If possible, I would also like to assign different weights to each of the evaluations, something like this: Positive = 1; Neutral = 0; Negative = -1.
Can you help me with the right formula to implemente it (and if possible with excel formula).
Thank you very much in advanced for you support.
BR,
