Question 865784
In words:
( average score ) = ( total of the 6 tests ) / 6
( total of the 6 tests ) = 6 x ( average score )
total of the 6 scores = {{{ 6*84 = 504 }}}
-----------------------------------
The remaining 2 tests add {{{ 200 }}} to the total score
and add {{{ 2 }}} to the number of tests
----------------------------------
Average = {{{ ( 504 + 200 ) / ( 6 + 2 ) }}}
Average = {{{ 704 / 8 }}}
Average = {{{ 88 }}}
