*Approximately what percentage of the 2018 students achieved a Grade B or higher?

Let's analyze the 2018 data from the bar graph.

- **Grade A (2018)**: 19 students
- **Grade B (2018)**: 24 students
- **Grade C (2018)**: 47 students

To find the percentage of students who achieved **Grade B or higher** (i.e., students who received either Grade A or Grade B), we first sum the number of students with Grade A and Grade B:

\[
\text{Total students with Grade A or B} = 19 + 24 = 43
\]

Next, we calculate the total number of students in 2018:

\[
\text{Total students in 2018} = 19 + 24 + 47 = 90
\]

Now, we calculate the percentage of students who achieved Grade B or higher:

\[
\frac{43}{90} \times 100 \approx 47.78\%
\]

So, approximately **47.8%** of the students in 2018 achieved a Grade B or higher.
