Question

On her drivers test, Mrs. Lynch got a 26 out of 30 questions correct.
The passing grade was 0.85. Did Mrs. Lynch pass?

Answer 1

To determine if Mrs. Lynch passed her driver's test, we need to calculate her score as a percentage and compare it to the passing grade of 0.85 (or 85%).

1. Calculate the percentage score:
\[
\text{Percentage Score} = \left( \frac{\text{Number of Correct Answers}}{\text{Total Questions}} \right) \times 100
\]
In this case:
\[
\text{Number of Correct Answers} = 26, \quad \text{Total Questions} = 30
\]
\[
\text{Percentage Score} = \left( \frac{26}{30} \right) \times 100 \approx 86.67\%
\]

2. Compare the percentage score to the passing grade:
- The passing grade is 85%.
- Mrs. Lynch's score is approximately 86.67%.

Since 86.67% is greater than 85%, Mrs. Lynch passed her driver's test.
