A punter's first four punts are 30 yd, 20 yd, 27 yd, and 29 yd. After a fifth punt, the punter's mean was 30 yd. How long was the fifth punt?

Let D be the distance of the last punt......and we have

 

[ 30 + 20 + 27 + 29 + D ] / 5  = 30

 

Multiply both sides by 5 and simplify

 

106 + D  =   150    

 

Subtract 106 from each side

 

D  =   44 yd
