Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Let x = score on 6th game
We have these 6 scores: 10, 14, 8, 18, 11, x
Add them up: (10+14+8+18+11+x)
Divide by 6: (10+14+8+18+11+x)/6
Set that quotient equal to 13, the average we want: (10+14+8+18+11+x)/6 = 13
-------------------------------------------------------
Now solve for x
(10+14+8+18+11+x)/6 = 13
10+14+8+18+11+x = 13*6
10+14+8+18+11+x = 78
61+x = 78
x = 78-61
x = 17
The team must score 17 points to average 13 points per game (over the 6 games played).
