0
To receive a C grade, a student must average more than
77 but less than or equal to
85. If Noah received a C in the course and had five grades of 73, 85, 75, 69, and
82 before taking the final exam, what were the possible grades for his final if there were
100 points possible? (Assume all six grades are weighted equally and let
x represent the unknown score.)

You can put this solution on YOUR website! To receive a C grade, a student must average more than 77 but less than or equal to 85.
If Noah received a C in the course and had five grades of 73, 85, 75, 69, and
82 before taking the final exam, what were the possible grades for his final if there were 100 points possible? (Assume all six grades are weighted equally and let x represent the unknown score.)
:
Let x = the lowest grade you can get and still have a C
 = 78
multiply both sides by 6
384 + x = 6(78)
x = 468 - 384
x = 84 will get you C
