Question

What percentage would my grade be if I got a 50% on a project that is worth 20% of my grade and my grade is 87%/B+.

How much would my grade go down?

Answer 1

78.3% which would be a C+

Explanation:

If the project was worth 20% of your grade and you got 50% on that project, we can multiply the decimal values of these percentages together to know exactly by how much your grade will drop.

0.2 * 0.5 = 0.1 or 10%

Now, we see that your grade will drop 10%. Meaning, that from your 87% you will actually have only 90% of that which is...

87 * 0.90 = 78.3

Therefore, your grade will go down to a 78.3% which would be a C+
