If i had a 65% in a course now, and i need a 70% to pass, What will i need to get on my final exam worth 25% to pass the course?

To determine the grade you need on your final exam in order to pass the course with a 70%, you can follow these steps:

Step 1: Identify the weight of your final exam
If the final exam is worth 25% of your overall grade, then it contributes 25% towards your final grade.

Step 2: Calculate your current grade
Your current grade in the course is 65%.

Step 3: Determine the remaining weight
The remaining weight is the percentage of your grade that is not accounted for by your current grade. In this case, it would be 100% - the weight of your final exam (100% - 25% = 75%).

Step 4: Determine the minimum grade required on your final exam
To find the minimum grade you need on your final exam, you can set up the following equation:
(Current Grade * Remaining Weight) + (Final Exam Grade * Weight of Final Exam) = Final Grade

In this case:
(0.65 * 0.75) + (Final Exam Grade * 0.25) = 0.70

Step 5: Solve the equation for the Final Exam Grade
Rearrange the equation to solve for the Final Exam Grade:
(Final Exam Grade * 0.25) = 0.70 - (0.65 * 0.75)

Final Exam Grade = (0.70 - (0.65 * 0.75)) / 0.25

By plugging in the values and solving the equation, the result will tell you the grade you need on your final exam to pass the course.
