For an average of least 125.2,what score in the 5th game is needed?

x = the needed score

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**
