Question

What is my overall grade if I scored 91.6 on a test that accounts for 90% of my grade, and the remaining 10% is a perfect score?

Options:
A) 91.6%
B) 92.5%
C) 93.0%
D) 94.0%

Answer 1

To find the overall grade, calculate the weighted average of the test score and the perfect score. The overall grade is 92.44%, closest to option B) 92.5%.

Step-by-step explanation:

To find your overall grade, you need to calculate the weighted average of your test score and the perfect score. First, calculate 90% of your test score by multiplying 91.6 and 0.9 which gives you 82.44. Next, calculate 10% of the perfect score by multiplying the perfect score (which is 100%) and 0.1 which gives you 10. Finally, add the two values together: 82.44 + 10 = 92.44.

Therefore, your overall grade is 92.44, which is closest to option B) 92.5%.
