Q: Which formula would you use to calculate the percentage grade for a student who scored 42 out of 50 on a lab exam?

$\text{Percentage} = \frac{42}{50} \times 100$

Q: Which equation would you use to determine the total grade if a student scored 85% on lecture (75% weight) and 90% on lab (25% weight)?

$\text{Total Grade} = (0.75 \times 85) + (0.25 \times 90)$
