Question 88839
Let x represent the sum of his scores. So when he divides the sum by 6 he gets:


{{{x/6=84}}}


{{{cross(6)x/cross(6)=6*84}}} Now multiply both sides by 6


{{{x=504}}} Multiply


So the sum of his scores is 504. Now divide 504 by 7 to find the correct average:


{{{Average=504/7=72}}}


So the correct average is 72
