if you orignailly scored a 57 on a test and took a retest and got a 62 and your overall grade in that class is 76, what will your grade be now?

To calculate your new grade after taking the retest, you need to take into account both the original score and the new score.

First, calculate the average of the original score (57) and the retest score (62):
(57 + 62) / 2 = 59.5

Next, calculate what percentage the average score is of the overall grade (76):
59.5 / 76 ≈ 0.78

Lastly, multiply the percentage by 100 to get your new grade as a percentage:
0.78 * 100 = 78

Therefore, your new grade after taking the retest will be approximately 78%.
