Answer 1

To determine the percentage of students who scored a B or higher, we first need to sum the values of the grades that are B or higher, which are grades B, A, and possibly any higher grades if applicable.

According to the data you provided:
- A = 8
- B = 12
- C = 5
- D = 3
- F = 2

Now we can add the students who scored A and B:

**Total who scored A or B = A + B = 8 + 12 = 20**

Next, we need to calculate the total number of students:

**Total = A + B + C + D + F = 8 + 12 + 5 + 3 + 2 = 30**

Finally, we can calculate the percentage of students who scored a B or higher:

\[
\text{Percentage} = \left(\frac{\text{Total who scored A or B}}{\text{Total students}}\right) \times 100 = \left(\frac{20}{30}\right) \times 100 \approx 66.67\%
\]

Rounded to the nearest tenth, the percentage of students who scored a B or higher is **66.7%**.

Thus, the correct response is **66.7%**.
