my grade is 83.17 in pre algebra in college, but the final exam is worth 300 points. If I got a B or B- or a C on the final, what would my grade be overall?

That depends upon the total number of points for the class.

it depends on the percent weight of the final exam. (e.g. 40% of your grade, 35% of your grade, etc.) assuming your grading scheme for a B is around 83%... and assume your final exam is worth 40% of your overall grade and the rest of your grade (83.17%) is 60% of your overall grade:

total grade= (0.8317 X 0.60) + (0.83 X 0.40) X 100% = 83.10%

that would be your grade if you got a B (ie. 83%) on your final. i hope you get the formula.

23 3/5 - 8 8/15

To calculate your overall grade after the final exam, you need to consider the weight of each component. Let's assume that the final exam is worth 300 points, and your current grade is based on a total of 1000 points.

First, calculate the portion of your grade that doesn't include the final exam. Since you received an 83.17 out of 1000 points, you earned (83.17/1000) * 700 = 58.22 points so far.

Now, let's consider the three scenarios you mentioned:

1. If you get a B on the final exam, which typically corresponds to a grade range of 80-89%, you will receive a score between 240-269 points (assuming your percentage is in the middle at 85%). Adding this score (let's take 255 points as an example) to your previous score gives you a new total of 58.22 + 255 = 313.22 points.

2. If you get a B- on the final exam, which typically corresponds to a grade range of 70-79%, you will receive a score between 210-239 points (assuming your percentage is in the middle at 75%). Adding this score (let's take 225 points as an example) to your previous score gives you a new total of 58.22 + 225 = 283.22 points.

3. If you get a C on the final exam, which typically corresponds to a grade range of 60-69%, you will receive a score between 180-209 points (assuming your percentage is in the middle at 65%). Adding this score (let's take 195 points as an example) to your previous score gives you a new total of 58.22 + 195 = 253.22 points.

Therefore, if you get a B on the final, your overall grade will be 313.22 out of 1000. If you get a B-, your overall grade will be 283.22 out of 1000. And if you get a C, your overall grade will be 253.22 out of 1000.
