You can put this solution on YOUR website! An arithmetic student needs an average of 70 or more to receive credit for the course. She scored 82, 64, and 98 on the first three exams. Write an inequality representing the score she must get on the last test to receive credit for the course.
------------------------
Let the last test score be "x".
EQUATION:
(82+64+98+x)/4>=70
244+x >=280
x >= 36
