88 average get a zero on final exam and final exam counts 20% of grade. what is my average

Question

say you have a 88 gpa in a class and you get a zero on the final exam. say the final exam counts 20% of your final grade. what is the final gpa after a zero?

Answer 1

Your grade before the final was 88.

 

Since the score on the final is a zero, the full 20% is deducted.

 

20% of your grade is 88(0.2) = 17.6

 

So your final grade is the original grade 88 minus the 20% (17.6)

 

88 - 17.6 = 70.4
