What will be the final grade in my Pre-calculus class if the teacher drops one test grade?

Question

I have taken all tests in my Pre Cal class and as of right now I have a 72.32. I was wondering since the teacher drops your lowest grade (which is 38 don't ask) what would my grade at the end of the semester be? All the test combined (6 total excluding the dropped one) except the one she drops account for 75% of my grade is what the syllabus says.

Answer 1

7 x 72.32 = 506.24

subtract the 38 to get 506.24-38 468.24

468.24/6 = 78.04 if the 38 is dropped

if 78.04 = 75% of your final grade, there must be another test? or another grade for homework or attendance? worth 25%

75% is 3/4 of the grade. 3(78.04)/4 = 58.53 if you got zero on the other 1/4 of the grade

if you received a 100 on the remaining 1/4 then 3(78.04) + 100 = 334.12/4 = 83.53

so you may get anywhere between 58.53 and 83.53, an F to a B. F, D, C, or B are possible.

depending on that other 25% of the grade.
