Question

a test is worth 50% of my grade. a get a 80% on the test. my grade rn is 54%. what's my grade after the test?

Answer 1

To calculate your new grade after the test, you can use the weighted average formula based on the percentages involved.

1. Your current grade is 54%, which is worth 50% of your final grade since the test is worth the other 50%.
2. You scored 80% on the test, which is also worth 50% of your final grade.

Using the formula for calculating the new grade:

\[
\text{New Grade} = (\text{Current Grade} \times \text{Weight of Current Grade}) + (\text{Test Score} \times \text{Weight of Test Score})
\]

Substituting the values:

\[
\text{New Grade} = (54\% \times 0.5) + (80\% \times 0.5)
\]

Calculating each part:

1. \(54\% \times 0.5 = 27\%\)
2. \(80\% \times 0.5 = 40\%\)

Now, add these two results together:

\[
\text{New Grade} = 27\% + 40\% = 67\%
\]

So, your grade after the test will be **67%**.
