27=.2x
135=x
Change it to 4.9 and x=550

Amazing. Thank you.
if I may ask 1 question:
let say in the process of gathering the 135 additional 5 scores hoping to get to 4.8, a score of 1 was given. How far back would it alone set the process? How many more 5 score would it then take to recover from the low score and get to a 4.8 ?
to my unmathematical mind, because there is much more room between 4.7 and 1 than there is between 4.7 and 5, a low score would have a more significant impact on the average than a high score would. Is this a truth?
