You can put this solution on YOUR website!
average is sum/n
sum for 4 is 1005
for an average at the end of 245, it has to have a total of 1225, because 1225/5=245
1225-1005=220
He needs a 220.
Check for 5
The first score is -10 below the average desired, the second 5 above, the third 5 below, the fourth 35 above, so he is 25 above going into the last game, and he can bowl 25 below the average of 220.
