Since the exam is worth 15%, your present grade is worth 100% - 15% or 85%.

So the formula is:

Overall grade = (.85)(.92) + (.15)(Exam grade) 

If your exam grade is 0%, your overall grade will be 78.2%
If your exam grade is 10%, your overall grade will be 79.7%
If your exam grade is 20%, your overall grade will be 81.2%
If your exam grade is 30%, your overall grade will be 82.7%
If your exam grade is 40%, your overall grade will be 84.2%
If your exam grade is 50%, your overall grade will be 85.7%
If your exam grade is 60%, your overall grade will be 87.2%
If your exam grade is 70%, your overall grade will be 88.7%
If your exam grade is 80%, your overall grade will be 90.2%
If your exam grade is 90%, your overall grade will be 91.7%
If your exam grade is 100%, your overall grade will be 93.2%
