Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! 79+72+67+75 = 293 points already earned.
If she needs at least 360 points, then she needs 360-293, or 67 points.
If the final is worth two test grades, then there are a total of 600 points possible.
For an A at 90%, she would need 540 (90% of 600). 540-293=247. Impossible since the highest she can get is 200 (a perfect score).
For a B at 80%, she would need 480. 480-293=187 out of 200 on the final, or 93.5%
For a C at 70%, she would need 420. 420-293=127 out of 200 on the final, or 63.5%
For a D at 60%, she would need 360. 360-293=67 out of 200 on the final, or 33.5%
