Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
To find the average, add the scores and divide by the number of scores.
x = the needed score
133 + 112 + 94 + 108 + x
------------------------- = 125.2 {added the scores and divided by the number of scores}
5
447 + x
-------- = 125.2 {added in numerator}
5
447 + x = 626 {multiplied each side by 5}
x = 179 {subtracted 447 from each side}
179 is the needed score
