In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Charles has scored 93, 82, and 87 on the first three. What range of scores on the fourth test will give Charles a C for the semester (an average between 70 and 79 , inclusive)? Assume that all test scores have a non-negative value.

Express your answer in interval notation.
