Q: Which equation best represents the calculation of body mass index (BMI), a physiological parameter often used in clinical settings?

$$\text{BMI} = \frac{\text{weight (kg)}}{\text{height (m)}^2}$$

Q: Which equation would you use to calculate the percent grade for a student who earned 85 points out of 100 on a lab practical?

$$\text{Percent Grade} = \frac{\text{Points Earned}}{\text{Total Points}} \times 100$$

Q: Which equation would you use to determine the total points needed to achieve a grade of 80% in a course with 1000 available points?

$$\text{Total Points Needed} = \frac{\text{Percent Desired}}{100} \times \text{Total Available Points}$$
