RE: Test Your Math Skills and Win SBD # 8
If all scored 100 then 500 + 35 is the low end score for average of 89
If all scored 90 then 450 + 85 is the high score for average of 89.

Answers are: 3,4,5,6,7,8
The lowest possible value, #8 would equal 89.16 - so yes, I am wrong if there are no fractions permitted...
I believe averages are rounded off.
