The average of Becky Jo's first two tests was 90. The average of her next eight tests was 95. What was her overall average? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! If her average in the 1st 2 tests was 90, then you
can say that she got 90 on each test ( even though
she probably didn't )
Likewise, you could say she got 95 on each of her next 8 tests
----------
The overall average is:
( sum of all her scores ) / ( number of tests she took )
Sum of scores was
Number of tests was
Her overall average was 94%
