If my total grade is a 68 in math and score a test thats worth 25% of my grade, what will my grade be
Step 1: Calculate the current weight of your grade without the test. Since the test is worth 25% of your grade, the remaining grade is worth 75%.
0.75 * 68 = 51
Step 2: Calculate the grade you received on the test. Let's say you received a grade of 80.
Step 3: Calculate the weighted average of your overall grade.
0.75 * 68 + 0.25 * 80 = 51 + 20 = 71
Therefore, your grade after taking the test will be a 71 in math.
