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.
----------
(75+63+68+x)/4 >= 70
Comment: The left side is the average of the four scores.
x is one of the scores; it is his score on the last test.
---------------
Cheers,
Stan H.
