Q: A student receives the following exam scores: 80, 75, and 90 out of 100. If the exams are worth 65% of the final grade, what is the student's exam average percentage contribution to the final grade? (Round to the nearest whole number.)

$$ \frac{80 + 75 + 90}{3} \times 0.65 = 81.25 $$

Q: A student’s homework average is 85%, their exam average is 78%, and their lab score is 92%. If the weights are: exams 65%, homework 15%, and lab 20%, what is the student’s final course percentage? (Round to the nearest whole number.)
