To calculate your total grade, we use the weighted average formula:

$\text{Total Grade} = (Weight_1 \times Grade_1) + (Weight_2 \times Grade_2)$

Here:

• $Weight_1 = 60\% = 0.6$
• $Grade_1 = 80\% = 0.8$
• $Weight_2 = 40\% = 0.4$
• $Grade_2 = 100\% = 1.0$

$\text{Total Grade} = (0.6 \times 0.8) + (0.4 \times 1.0)$

$\text{Total Grade} = 0.48 + 0.4 = 0.88$

Convert back to percentage:

$\text{Total Grade} = 88\%$

Your total grade is 88%.

1. How is a weighted average different from a simple average?
2. What happens if one weight is adjusted higher or lower?
3. How does this method apply to other grading systems?
4. What if the percentages don't add up to 100%?
5. Can this method be used in real-world financial calculations?

Tip: Always double-check the weights and grades to ensure they sum correctly to 100%.
