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
