Solve the problem by using a compound inequality. See Example 12.

Aiming for a C. Professor Johnson gives only a midterm exam and a final exam. The semester average is computed by taking of the midterm exam score plus of the final exam score. To get a C, Beth must have a semester average between 70 and 79 inclusive. If Beth scored only 64 on the midterm, then for what range of scores on the final exam would Beth get a C?
