Question 973907: Joanna has bowled 4 games this week and her average for those games is 175, She bowls one more game and raises her average for the week to 179. What was her score in the last game? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! average=total/number
total=average*number=175*3=525
179= new total/4 She will have bowled another game.
4*179 is new total=716.
new total-old total=716-525=191
She must bowl 191.
