if my grade is an 89 and I get a 75 on a portfolio that is worth 64% of my grade what is my new grade?
To calculate your new grade, you need to consider the weightage of the portfolio in your grade calculation.
Let's assume the portfolio is worth 64% of your grade, and the rest of your grades are weighted at 100 - 64 = 36%.
Since your current grade is 89 (out of 100), the weighted value of your current grade is 89 * 36/100 = 32.04.
Now, let's calculate the weighted value of your portfolio grade, which is 75 * 64/100 = 48.
To find your new grade, you need to sum up the weighted values of your current grade and the portfolio grade:
New grade = Weighted value of current grade + Weighted value of portfolio grade
= 32.04 + 48
= 80.04
Therefore, your new grade would be approximately 80.04%.
