Question

Jorge's math grade is calculated using a weighted average. Quizzes are worth 30%, homework is worth 10%, unit tests are worth 40%, and the final exam is worth 20%.
Jorge earned an average of 92% on his quizzes, 98% on his homework, 91% on his unit tests, and a score of 95% on his final exam.

What is Jorge's final math grade?

Answer 1

By rewriting the weights in decimal form and applying them to the correspondent percentages, we will see that the final grade is 92.8%.

What is Jore's final math grade?

The final grade will be given by:

G = a₁*x₁ + a₂*x₂ + ...

Where the values "a" are the weights, and the values "x" are the averages of Jeorge.

We know that the weights are:

• 30% on Quizzes.
• 10% on homework
• 40% on unit test.
• 20% on the final exam.

Then we can write the weights in decimal form:

a₁ = 0.3

a₂ = 0.1

a₃ = 0.4

a₄ = 0.2

And the scores are:

• 92% on quizzes.
• 98% on homework
• 91% on unit tests
• 95% on final exam.

So the final math grade will be:

G = 0.3*92 + 0.1*98 + 0.4*91 + 0.2*95 = 92.8%
