Q: If a student scores 78% on exams, 85% on homework, and 90% on lab, what is their final grade percentage? (Exams: 65%, Homework: 10%, Lab: 25%)

$$0.65 \times 78 + 0.10 \times 85 + 0.25 \times 90 = 50.7 + 8.5 + 22.5 = 81.7\%$$

Q: If a student receives 60% on the exam portion of the course, what is the highest possible final grade they can achieve, assuming perfect scores in homework and lab? (Exams: 65%, Homework: 10%, Lab: 25%)

$$0.65 \times 60 + 0.10 \times 100 + 0.25 \times 100 = 39 + 10 + 25 = 74\%$$

Q: A student has a lab average of 80%, homework average of 90%, and exam average of 70%. What is their final grade percentage? (Exams: 65%, Homework: 10%, Lab: 25%)

$$0.65 \times 70 + 0.10 \times 90 + 0.25 \times 80 = 45.5 + 9 + 20 = 74.5\%$$
