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.

Please explain how I am to do this?

Hint: How does one find the average of four values? :wink:

remember that he can't get over 100% on his last test (unless they do that extra score thing)..

Do you not have a math teacher?
Or are you learning on your own?
