You can put this solution on YOUR website! Sam must have an average of 70 or more in his summer course to obtain a grade of C. His first three test grades were 75, 63, and 68. Write an inequality representing the score that Sam must get on the last test to get a C grade.
------------------
Let "x" be the score on the last test.
--------------------------
INEQUALITY:
(75+63+68+x)/4 >= 70
