Suppose you get zero on the final, which is 10% of the grade. It looks like you have 70% of the remaining 90%, which is

0.70(90%) = 63%

So if you get a zero on the final, your overall score is 63%. What letter grade is 63%?

Arturo O.

Well, that contradicts what you said in the problem statement, where you said you have 70% on the rest of the grade. What percent of the total grade is geometry? Call that P

_{1}. What is your average score in geometry? Call that S_{1}. What is your average score in the remaining percentage of the grade, where the remaining percentage is 100 - P_{1}? Call that score S_{2}. Then your overall numerical score S isS = [P

_{1}S_{1}+ (100 - P_{1})S_{2}] / (P_{1}+ P_{2})Plug in the numbers, compute S, and see in what letter grade range it falls.

Geometry is the class. He has A's in his other classes.
