If I have a 60% in my class and I score a 75% on my summative that is worth 15% of my mark. What is my current grade afterwards?

To determine your current grade after scoring 75% on a summative worth 15% of your mark, you need to calculate the weighted average.

Let's assign a variable to represent your current grade. We'll use "G" for this.

Since the summative is worth 15% of your mark, the remaining 85% is your current grade.

Your current grade (G) is equivalent to 85% of your previous grade (60%).

Therefore, you can calculate the current grade as follows:

G = 0.85 * 60% + 0.15 * 75%

G = 0.51 + 0.1125

G = 0.6225

Your current grade, rounded to the nearest whole number, is approximately 62%.
